▼ Global warming is becoming an increasingly important environmental concern and CO₂ is considered as the major cause of global warming. Creating useful applications for CO₂ would generate alternatives to merely venting CO₂ to the atmosphere, and decreasing the carbon intensity of human activities. Among various methods of CO₂ utilization, conversion of CO₂ to value-added chemical products is the most attractive. In this study, microtechnology and application of corona discharge are combined and introduced into CO₂ reduction process. Experiments were conducted before the design and manufacture of the microreactor to determine the configuration of the reactor, products of reaction and effect of active volume ratio: (1) it is proved that through-gas corona discharge are much simpler to implement than through-liquid, especially those with high solubility of CO₂; (2) the V-I curve for the corona discharge reactors is characterized by a transition from a high voltage low current (which we call spark discharge) to a low voltage high current state (the corona discharge state), with this transition used as a diagnostic of the reactor operation in the corona discharge mode even when direct observation of the discharge is not practical; (3) the products for the reduction of dry CO₂ are carbon monoxide (CO) and oxygen (O₂), while for the reduction of wet CO₂, methane (CH4) is also formed in addition to these two products; (4) a larger active volume ratio results in higher conversion of CO₂ to products. Based on the experimental results listed above, two multi-discharge microscale-based corona reactors were designed and manufactured. We found that for a needle-to-plate gap of 110μm, at the voltage of 0.840kV and current of 0.62mA, a flow of CO₂ and H₂O mixture (flow rate of CO₂ = 50sccm, CO₂-to-H₂O molar ratio = 1:2) can result in 5.5~6% conversion of CO₂ (with 40~50% conversion within the active volume of the reactor) with energy efficiency of 85~95%. The influence of the three main factors, namely the power applied to the reactor (specific points of the V-I curve used), flow rate of CO₂, and CO₂-to-H₂O molar ratio, on the performance and energy efficiency of the reactor were investigated. It was found that (1) the glow regime (or corona regime) is the optimal operation regime for this process from both conversion and energy efficiency perspectives, with higher current in this regime resulting in higher CO₂ conversion; (2) lower flow rate of CO₂ can result in higher conversion with lower energy efficiency, and conversely, the highest energy efficiency is achieved at the highest flow rate; (3) the conversion of CO₂ increases as the CO₂-to-H₂O molar ratio decreases, but the highest energy efficiency is achieved when this ratio matches the ratio of stoichiometric numbers. A numerical model of the process reflecting the geometry, momentum balance, material balance and kinetics inside the reactor was developed to help understand the chemical reaction process. The reaction scheme was modelled as… Advisors/Committee Members: Jovanovic, Goran (advisor), Arnadottir, Liney (committee member).

▼ In addition to reducing carbon dioxide (CO2) emissions from fossil fuel combustion, removing atmospheric CO2 may be critical to limit global warming to less than two degrees Celsius above pre-industrial levels recommended by leading experts. Since cropland occupies 11% of the earth’s land and is intensively managed, cropland agriculture provides one approach for removing CO2 from the atmosphere to mitigate climate change. However, current assessments indicate agriculture is a net emitter of CO2 and other greenhouse gases, and it is unclear how soil management can effect carbon sequestration.In this work micrometeorological methods are used to measure the exchange (flux) of CO2 between the surface and atmosphere and can assess whether an agricultural ecosystem is a source or sink for carbon. Three studies were performed using micrometeorology to understand agriculture’s potential to sequester carbon.Using Bowen Ratio Energy Balance (BREB) micrometeorological methods, the first study measured CO2 flux from a maize crop grown on no-till and tilled soils to determine tillage effects on CO2 emissions during 104 days of the 2015 maize growing season in north central Ohio. During this period, the no-till plot sequestered CO2, while the tilled plot was a net emitter.A second study determined if industrial biotechnology waste reutilization in agriculture could reduce CO2 emissions and generate environmental benefits, while meeting farmer yield expectations. Using both BREB and eddy covariance (EC) micrometeorological methods, CO2 flux was measured over maize where heat-inactivated, spent microbial biomass (SMB) amendment was land applied and compared with typical farmer practices from October 2016 to October 2017 in Loudon, Tennessee. While treatments with SMB emitted more CO2 than farmer practices, the SMB applications produced yields similar to farmer practices.Using BREB micrometeorology methods, the third study measured CO2 emissions over conservation agriculture (CA) practices as compared to conventional tillage from June 2013 to May 2016 in central Zimbabwe. The CA practices of no-till and cover crops produced significantly fewer CO2 emissions than conventional tillage.These studies demonstrate that micrometeorology can detect short- and long-term differences in CO2 flux between practices, providing data supporting agriculture’s potential to reduce CO2 emissions and sequester carbon.

▼ More than 60% of the original oil in place (OOIP) is left in the ground after the primary and secondary recovery processes. With the introduction of enhanced oil recovery (EOR), that number goes down to about 40% of the OOIP. Carbon dioxide (CO2) injection is one of the most effective EOR methods in naturally fractured reservoirs. The fracture network provides a faster means for fluid flow due to its high conductivity but it is also the cause of premature breakthrough of the injected fluids. However, if employed efficiently, fractures can help push the injected CO2 to the reservoir boundaries so that a large portion of the reservoir fluid interacts with the injected CO2. Zones swept by miscible CO2 reported the lowest residual oil saturation. Continuous CO2 injection is becoming more and more preferred to the popular cyclic pressure pulsing. Continuous CO2 injection has no down time and could potentially provide better CO2 interaction with the reservoir fluid which provides a higher recovery. In this research, artificial neural networks (ANNs) are used to construct robust proxy models with highly predictive capabilities for naturally fractured reservoirs undergoing continuous CO2 injection. The main purpose of this research is to shed more light and understanding on continuous CO2 injection in naturally fractured reservoirs and provide a tool that empowers engineers to make decisions on the fly while evaluating uncertainty and mitigating risk rather than wait months or years to do so. In light of the above, various ANN designs and configurations undergo development and evolution to ultimately be able to provide valuable insights regarding reservoir performance, history matching, and injection design for naturally fractured reservoirs undergoing CO2 injection. Initial ANN designs targeted specific reservoirs using specific fluid compositions from the literature. The designed ANNs were able to provide predictions with a low degree of error. ANN designs went over many complex adjustments, variations, and enhancements until final configurations were reached. The final ANN designs developed in this research surpass previously developed ANNs in similar projects with its capability to handle a huge range of reservoir properties, relative permeability, capillary pressure, and fluid compositions under uncertainty. The reservoir simulation model used in this research is a two-well, two-layer, miscible compositional simulation model working in a dual-porosity system. Critical parameters affected the accuracy and predictability of the ANN designs and they were an essential part of the final ANN configurations. The parameters that a major effect on continuous CO2 injection are reservoir fluid composition, fracture permeability, well spacing, bottomhole flowing pressure (BHFP), thickness, and CO2 injection amount under miscible conditions had the highest impact on recovered oil. The final ANN designs were encompassed inside a graphical user interface that equipped the ANN with uncertainty evaluation capabilities. The ease to use… Advisors/Committee Members: Turgay Ertekin, Dissertation Advisor/Co-Advisor.

▼ Mineral carbonation is one of the most appealing CO2 emission mitigation techniques capable of storing CO2, in the thermodynamically stable states. However, the technical mineralization process faces serious challenges, in regard to the reaction kinetics and issues with high energy intensity. Pre-activation techniques such as mechanical activation are proposed as effective strategies to enhance the kinetics of mineral carbonation processes. They however, significantly increase the total energy consumption of the processes and hence, optimizing the energy needed for pre-activation process is essential. Mechanical activation technique was performed, using a Uni-Ball-Mill 5. The variation of determinant structural parameters such as particle size, specific surface area, pore volume, crystallite size and crystallinity was recorded as a function of injected milling energy input, using SEM, BET and XRD analysis techniques. Considering the outcomes of this research stage, the optimal level of pre-activation milling energy for the most suggested microstructure for CO2 storage was found to be about 55 kJ/g. Energy optimization and kinetics enhancement was then considered and expanded to the field of reactive compound extraction. Milling energy inputs of 0, 13.8, 27.6, 41.4 and 55.2 kJ/g were injected for the purpose of the reactants’ pre-activation. Solid state extraction was performed under the isothermal conditions of 400, 425 and 450 ̊C in a combined DSC/TGA thermal analyzer device (NETZSCH STA 449F3A-0918-M Jupiter). The trend of activation energy variation vs. milling energy input was calculated and monitored to find the optimal amount of milling energy input needed to produce the structural properties with the lowest amount of activation energy for the solid state extraction process. The calculated amount of optimal milling energy input, to address the objective of this phase of study was found to be about 27.6 kJ/g. This resulted in an almost 34% reduction in the activation energy of MgSO4 solid state extraction. Complimentary to the goal of enhancing the kinetics and performance of the mineral carbonation process, the enhancement of directed anhydrous carbonation was examined as a next stage of research. Two different strategies were followed to address this objective, including the optimization and control of carbonation parameters (temperature and pressure), and the implementation of heterogeneous precipitation, in order to promote the possibility of formation of anhydrous carbonation products during the aqueous carbonation of Mg(OH)2 powders. Carbonation reactions were performed in a 4650 Parr high-temperature high-pressure reaction vessel. Carbonation temperatures of 100, 150 and 200 ̊C and CO2 pressure of 10, 20, 25 and 30 bars, were used. This stage of study confirmed the noticeable influence of carbonation temperature on the formation of anhydrous carbonates, and on the enhancement of directed carbonation. As a continuation, the effects of the implementation of preferred precipitation sites on the…

▼ Concerns arising from the effects of carbon dioxide emissions on the global climate mean that CO2 is almost always portrayed in a negative light. The result of this reputation is that the potential of CO2 as a cheap, safe and green alternative to many hazardous and toxic feedstock chemicals is often overlooked. With virtually unlimited availability, CO2 has the potential to be a sustainable source of industrial carbon in a world with finite petroleum reserves. This thesis provides an in-depth examination into several novel methods to utilize CO2 as a feedstock rather than discarding it as a byproduct. The first section of the work describes an original process for the high-yield conversion of CO2 to formic acid by reduction with potassium borohydride under ambient conditions. The mechanism of the reaction was probed through isotopic labelling using a time-resolved in situ 1H and 11B nuclear magnetic resonance (NMR) technique developed especially for this task. The formation of H2, HD and a hydroxyborohydride intermediate (BH3OH-) was directly observed and enabled the reaction mechanism to be established. The second section of the thesis describes the development of heterogeneous mixed oxide catalysts for the cycloaddition of CO2 to propylene oxide for propylene carbonate synthesis. A custom high pressure reactor was designed and built for this task. A Ca:Zn:Al/Na mixed oxide material was developed and it was discovered that the interface at the junction between co-deposited ZnO and NaAlO2 nanoparticles is of critical importance for the promotion of the cycloaddition reaction with this material. An alternative material in which ZnO quantum dots are homogenously distributed within an amorphous spherical silica matrix was also found to be active towards this reaction. An original synthesis method is presented whereby the ZnO quantum dots are grown in situ via a novel dissolution/re-deposition mechanism and encapsulated during the simultaneous precipitation of tetraethyl orthosilicate (TEOS) at room temperature. The mechanism by which this process occurs is explored in depth via XRD, TEM, STEM-EDS, Raman and thermogravimetric methods.

▼ Fluxes of carbon dioxide (CO₂), being a major greenhouse gas, are of great importance to understand and monitor. Findings have shown that while CO₂emissions enhanced by humans triggered the greenhouse gas effect, several significant CO₂fluxes in nature that are climate sensitive may still be poorly constrained, especially those from inland waters and its surrounding soils and sediments. This including different processes such as decomposers degrading organic material. At present, direct measurements of CO₂ from soils, waters or CO₂concentrations in surface water, are typically labour intensive or require costly equipment. Therefore, small inexpensive CO₂mini loggers, originally made for indoor air quality monitoring, are for this project being developed further for field use, as a convenient equipment to measure CO₂emissions. However, a requirement is that the mini loggers are stable and robust against interference by other air components, including water vapour, and physical factors such as temperature. Therefore, the mini loggers were for this project studied further under different environmental conditions such as temperature and humidity in a controlled environment. The results were analysed using multiple regression analysis where the CO₂concentration (CO₂), measured by the LGR instrument, versus the logger IR signal (IR), temperature (T) and relative humidity (RH) were studied. Unlike some previous studies, this project studied a large CO₂concentration interval (400 – 10 000 ppm). The results show that there was a strong regression for IR versus CO₂. The regression for both RH and the T was on the other hand very weak. However, there were factors that could have affected the mini logger. This since it was noticed that the mini loggers’ ability to calculate the CO₂concentration was worsened when the humidity was increased during the experiments. It is believed that the cause was condensed water, gathering in the inner parts of the mini logger. This because the sensor chamber had a lower temperature than the hot air entering the sensor chamber from the humidity bottle, together with the CO₂, leading to condensation. Hence, prevention of condensation inside the measurement cell is important. However, the results from the analysis shows that the factors; RH and T do not need to be taken into account when studying the CO₂concentration over a larger interval, as long as the conditions are not condensing.

▼ The link between a good indoor climate and environmental impacts e.g. global warming and different pollution in the air is something that are important today and will certainly become more important in the future with increased energy prices and new laws. Too keep the indoor air quality within limits is it important to have a good and competitive ventilationsystem. The ventilations function is mainly to supply fresh air and to remove polluted air from the room. It’s important that the ventilation system works as it should so that the indoor air quality is as good as possible. The lack of good ventilation can create several symptoms such as headaches, nausea, fatigue, poor concentration etc. In Sweden are ventilation control mandatory for every newly produced building and this control are repetitive usually every 3-6 years for some types of buildings. The foundation of this thesis is from a previous degree project performed by a master’s student in 2013 named Ander Barroeta with supervision of Magnus Mattsson and Taghi Karimipanah. The thesis was to improve and design a ventilation system in two rooms at a training facility named Friskis & Svettis in Gävle so that the CO₂ level did not exceed 1000 ppm. In this thesis was the main goal to do similar measurements as the previous thesis and compare the results to see what difference air balancing has done to the ventilation system. Field measurements were performed at the training facility were the focus was on carbon dioxide but also on other parameters such as temperature, humidity and air velocity so that air exchange rate could be calculated. With these parameters can evaluations be made to see if air balancing of the ventilation system made any difference in indoor air quality. During measurements in one of the training rooms where spinning is exercised was carbon dioxide levels up to 3300 ppm measured which is above the recommended indoor limit at 1000 ppm. If that room should be design to not exceed 1000 ppm must the air exchange rate increase from 6.3 h^-1 to 35.1 h^-1.

▼ The concentration of carbon dioxide ([CO2]) in the atmosphere is predicted to reach 730 – 1020 parts per million (ppm) by 2100, and the risk of drought is predicted to increase. Elevated atmospheric [CO2] directly affects C3 plants by reducing stomatal conductance (gs) and increasing photosynthetic carbon assimilation (A). It is widely hypothesized that reduced gs in elevated [CO2] will decrease plant and canopy water use, conserving soil moisture and ameliorating drought stress. Additionally, stimulation of A by elevated [CO2] often results in increased root biomass, and this is predicted to improve plant access to soil water, enabling avoidance of drought stress. Models of future food supply often assume that these beneficial effects of elevated [CO2] will compensate for the predicted increases in drought stress, but this assumption has not been widely tested in realistic crop production environments. However, elevated [CO2] also increases canopy temperature and leaf area, both of which have the potential to compensate for the effects of reduced gs on canopy water use, and the extent to which this compensation occurs in the field is not well understood. Furthermore, it is not known how stimulation of root growth by elevated [CO2] will alter the distribution of root length relative to soil water resources, or how this may affect whole plant water status, and, in the case of legumes, the symbiosis with nitrogen-fixing bacteria. These knowledge gaps were addressed at the soybean Free-Air CO2 Enrichment (soyFACE) facility, where soybean was grown in the field at ambient [CO2] or elevated [CO2], as predicted for the middle of this century. I analyzed an eight year field study to test the hypothesis that reduced gs in elevated [CO2] will overwhelm increases in leaf area and canopy temperature to result in conservation of soil moisture. Additionally, I conducted a three-year experiment where a sub-plot of each ambient and elevated [CO2] treatment plot was exposed to reduced precipitation to test the prediction that, by allowing avoidance of drought stress through conservation of soil water and stimulation of root growth, elevated [CO2] will reduce drought sensing and signaling via the plant hormone abscisic acid, and will ameliorate drought-induced reductions in photosynthetic gas exchange. I also tested the predictions that elevated [CO2] will increase the production and size of nitrogen-fixing root nodules, reduced precipitation will inhibit nodule production, and elevated [CO2] will ameliorate the negative effects of reduced precipitation on nodule production. I found that elevated [CO2] did not always conserve soil water, and increased root length in elevated [CO2] occurred in shallow or intermediate soils which tended to be dry, resulting in no improvement in access to soil water and negative effects on plant nitrogen status. Furthermore, I found that elevated [CO2] caused stomata to respond more sensitively to abscisic acid, often resulting in greater drought-induced reductions in photosynthetic gas exchange in… Advisors/Committee Members: Leakey, Andrew D.

▼ Supercritical carbon dioxide is injected into underground formations to enhance oil recovery and for subsurface sequestration to minimize the impact of CO2 emissions due to global warming. The complex phase behavior of CO2 with oil determines the effectiveness of the CO2 injection for enhanced oil recovery. The injection of CO2 into the subsurface is also affected by the large and small scale heterogeneities in the formations. These two aspects of CO2 injection are examined in this research. Development of multiple-contact miscibility is important in the success of a carbon dioxide enhanced oil recovery. CO2 displacements are often designed to operate above the minimum miscibility pressure (MMP) to ensure the development of multiple contact miscibility between the oil and CO2. Compositional histories in different parts of a two-dimensional domain are examined in this study in relation to displacement pressure employed. The second part of this dissertation deals with the effect of faults on the CO2 sequestration process and on the integrity of storage. Outcrop-based studies of faulted, aeolian Navajo sandstone provide detailed, quantitative insight regarding the range of fault characteristics that might be encountered as injected CO2 migrates through the faulted aquifer. Faults can act as barriers, conduits, or integrated barrier-conduit systems. Uncertainty in knowing whether a subsurface fault will act as a barrier or conduit leads to uncertainty in evaluating the likelihood for economically sequestering CO2 in sandstone aquifers. EclipseR black oil reservoir simulator is used to explore how different, 3-D, fault-related permeability/porosity structures might impact CO2 injection into, migration through, and leakage from a sequestration aquifer. Sandstone permeability values range from 10s to 1000s of mD. Simulator output shows how fault conduits and barriers can restrict migration of CO2 through the aquifer as a consequence of bypassing (conduits) or compartmentalization (barriers). In addition, the simulation results reveal how the geoscientists’ ability to quantify and discriminate between high-permeability versus low-permeability faults in sandstone aquifers can play an important role in designing CO2 sequestration operations.

Chemistry

Carbon dioxide (CO2) is formed when fossil fuels such as oil, gas and coal are burned in power producing plants. CO2 is naturally found in the atmosphere as part of the carbon cycle, however it becomes a primary greenhouse gas when human activities disturb this natural balanced cycle by increasing levels in the atmosphere. In light of this fact, greenhouse gas mitigation strategies have garnered a lot of attention. Carbon capture, utilization and sequestration (CCUS) has emerged as a possible strategy to limit CO2 emissions into the atmosphere. The technology involves capturing CO2 at the point sources, using it for other markets or transporting to geological formations for safe storage. This thesis aims to understand and probe the chemistry of the reactions between CO2 and iron-bearing sediments to ensure secure storage for millennia. The dissertation work presented here focused on trapping CO2 as a carbonate mineral as a permanent and secure method of CO2 storage. The research also explored the use of iron-bearing minerals found in the geological subsurface as candidates for trapping CO2 and sulfide gas mixtures as siderite (FeCO3) and iron sulfides. Carbon dioxide sequestration via the use of sulfide reductants of the iron oxyhydroxide polymorphs lepidocrocite, goethite and akaganeite with supercritical CO2 (scCO2) was investigated using in situ attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The exposure of the different iron oxyhydroxides to aqueous sulfide in contact with scCO2 at ~70-100 ˚C resulted in the partial transformation of the minerals to siderite (FeCO3). The order of mineral reactivity with regard to siderite formation in the scCO2/sulfide environment was goethite < lepidocrocite ≤ akaganéite. Overall, the results suggested that the carbonation of lepidocrocite and akaganéite with a CO2 waste stream containing ~1-5% H2S would sequester both the carbon and sulfide efficiently. Hence, it might be possible to develop a process that could be associated with large CO2 point sources in locations without suitable sedimentary strata for subsurface sequestration. This thesis also investigates the effect of salinity on the reactions between a ferric-bearing oxide phase, aqueous sulfide, and scCO2. ATR-FTIR was again used as an in situ probe to follow product formation in the reaction environment. X-ray diffraction along with Rietveld refinement was used to determine the relative proportion of solid product phases. ATR-FTIR results showed the evolution of siderite (FeCO3) in solutions containing NaCl(aq) concentrations that varied from 0.10 to 4.0 M. The yield of siderite was greatest under solution ionic strength conditions associated with NaCl(aq) concentrations of 0.1-1 M (siderite yield 40% of solid product) and lowest at the highest ionic strength achieved with 4 M NaCl(aq) (20% of solid product). Based partly on thermochemical calculations, it is suggested that a decrease in the…

▼ For decades Exhaust Gas Recirculation (EGR) has been used to mitigate several issues related to gas turbine operation: CO2 sequestration; NOx formation and emission; and combustor instabilities. EGR increases CO2 concentrations in turbine exhaust for more efficient CO2 scrubbing, reduces NOx emissions, and reduces combustor instability associated with pressure resonances. As EGR technology has developed, EGR ratios have continued to increase and introduce greater amounts of combustion products, primarily CO2, as part of the oxidizer in gas turbines. The goal of this study was twofold: to observe the role excess amounts of CO2 play in causing non-idealities, bifurcation in particular, in shock-tube experiments using real (non-dilute) fuel-air mixtures, and to experimentally examine the kinetic effect, if any, of excess amounts of CO2 as part of natural gas fuel-oxidizer mixtures. Experiments were performed in a shock-tube facility on the campus of Texas A&M University. Mixtures were composed of a representative natural gas mixture at an equivalence ratio of ϕ = 0.5 using modified oxidizer compositions representative of those used in EGR turbines. These oxidizer compositions maintained constant levels of O2 while exchanging N2 for CO2 in stages to give oxidizer mixture concentrations ranging from (0.21O2+0.79N2) to (0.21O2+0.79CO2) with intermediate combinations of N2/CO2 in between. Low-pressure and high-pressure (near 1 atm and 10 atm, respectively) experiments were conducted over an approximate temperature range of 1450-1900 K for the simulated EGR mixtures. Upon conclusion of all experiments and analyses, the observed effect of CO2 relating to reflected-shock bifurcation was quite significant, giving stronger bifurcation as amounts of CO2 increased, as determined by a sidewall pressure transducer. However, the observed kinetic effect of CO2 on ignition delay time was quite small in comparing ignition delay times with and without CO2. A modern chemical kinetics model also predicts that the effect of CO2 dilution on methane ignition delay times at the conditions herein are very small, within the uncertainty of the experiments. This result helps to confirm the validity of the measured results. One can also conclude that despite the significant bifurcation and proportionately increased uncertainty in the test conditions as a result, the ignition delay time results herein seem to indicate that the test conditions are still at the nominal temperature and pressure as derived from the speed of the incident shock wave in the conventional way.

▼ New fracturing techniques have helped to unlock the once unrecoverable oil from unconventional reservoirs. Unfortunately, even with newer technologies, there are still resources in place that the industry is leaving behind mainly because there is a lack of understanding on how to efficiently exploit them. For example, while hydraulic fracturing may create the conduits for oil to flow, it may not be a readily applicable technology in a complex and highly heterogeneous media like the Chicontepec field in Mexico, and a need arises for EOR techniques to be studied. This research focuses in simulating, history matching and analyzing a CO2 pilot test executed in the Chicontepec field. Fluid compositions, lab tests, and reservoir properties are provided based on a 40 x 40 x 40 grid. Also, pressure and production data are available for the wells. First, a fluid model is created and tuned to match the lab tests. Then the reservoir model is completed and upscaled to improve CPU performance while avoiding loss of accuracy. The history match honors CO2 injection rates while retaining both pressure and rate control. Based on the best match, new scenarios are run to study the effect of different injection rates and volumes. Finally, dimensionless injection vs recovery curves are created based on simulation forecasting. While the pilot test did not achieve the expected results, valuable insight was gained that will drive future projects. First, hydrocarbon pore volume injected (HCPVI) was too small to create a production response on off-set wells. Nevertheless, the extension of the hydraulic fracture on the injector well plays a key role in the early breakthrough observed in the one and only well in which CO2 breakthrough was observed. The geomechanical aspects of the fracture are not studied in detail but are proven to affect the numerical simulation. Finally, a few observations regarding the ideal data acquisition program are provided. Advisors/Committee Members: Schechter, David S. (advisor), Barrufet, Maria A.

▼ Ocean acidification may cause biodiversity loss, alter ecosystems and impact food security, yet uncertainty over ecological responses to ocean acidification remains considerable. Most work on the impact of ocean acidification on foraminifera has been short-term laboratory experiments on single species. To expand this, benthic foraminiferal assemblages were examined across shallow water CO2 gradients in the Gulf of California, off the islands of Ischia and Vulcano in Italy and off Papua New Guinea. Living assemblages from the Gulf of California did not appear to show a response across a pH range of 7.55 – 7.88, although the species assemblage was impoverished in all locations and the dead assemblage was less diverse at the lowest pH sites where there was evidence of post mortem dissolution. At Vulcano, the small macroalga, Padina pavonica, did not protect calcareous foraminifera from the adverse effects of ocean acidification. Calcareous taxa disappeared from the assemblage and were replaced by agglutinated foraminifera as mean pH reduced from 8.19 to 7.71. Settlement of benthic foraminifera onto artificial collectors off Vulcano was adversely affected in the acidified water, with few species as pCO2 increased and evidence of post-mortem dissolution. The foraminiferal tests, collected off Papua New Guinea, had lower δ11B as mean pH decreased from 7.99 – 7.82 for small (250 – 500 µm) Amphistegina lessonii, but not for A. lessonii or Calcarina spengleri >500 µm. In the larger foraminifera, photosynthetic activity by symbionts may begin to dominate the boron isotopic signature. Overall, the responses of foraminiferal assemblages to ocean acidification are complex, but there was an overall reduction in species diversity in infaunal, epifaunal and epiphytic assemblages as pCO2 increased. This raises serious concerns for the survival of shallow water calcareous benthic foraminifera as the oceans continue to acidify, with implications for benthic ecosystems and inorganic carbon cycling.

▼ The anticipated negative impacts of climate change have prompted efforts to remove excess CO2 from the atmosphere, as well as prevent it from reaching the atmosphere in the first place. Following capture from point emissions sources or directly from the air, CO2 can be transformed into a diverse portfolio of carbon-containing products with both societal and economic value. Electrochemical reduction is an attractive means of converting CO2 into these products, but catalysts capable of facilitating this chemistry are plagued by large energetic requirements, poor selectivities, or limited product distributions. Of all pure-metal electrodes, only copper generates a wide distribution of highly reduced, multi-carbon products, but initial reports of bimetallic catalysts indicate the possibility of unlocking copper-like catalytic behavior using alloys. In this work, bimetallic alloy, intermetallic, and oxide species combining non-CO2-reducing transition metals and Group 13 metals are studied for their electrocatalytic activity toward CO2, emphasizing three different areas of development: (1) catalyst discovery, (2) catalyst tuning, and (3) mechanistic evaluation. Two new electrocatalysts are shown to produce multi-carbon chemicals from CO2 and serve as formative case studies in higher-order product generation. Namely, a Cr2O3/Ga2O3 alloy produces oxalate in aqueous solution at unprecedented Faradaic efficiencies, overturning historically accepted mechanistic requirements, while the Ni3Al intermetallic serves as the first non-copper-containing electrocatalyst capable of generating three-carbon products from CO2. Furthermore, tuning the intermetallic catalyst Ni3Ga is achieved by altering its carbon solid support and material structure. Carbon supports are demonstrated to exert morphological and surface compositional control over Ni3Ga during synthesis, thereby impacting reactivity toward CO2 during electroreduction. This sort of tuning can be exploited in catalyst design or optimization efforts, as can an understanding of CO2 reduction pathways activated by combining transition metals and Group 13 metals in electrocatalysis. Preliminary insight into this latter point is gained by studying a series of spinel oxides, which differentiate between CO- and formate-dependent CO2 reduction pathways. Ultimately, the progress reported in each of these areas of catalyst development—discovery, tuning, and mechanistic analysis—motivates ongoing CO2 conversion research and supports the goal of implementing CO2 utilization strategies for profitable environmental remediation.

▼ Gas separation membranes of high CO2 permeability and selectivity have great potential in both pre and post-combustion CO2 capture from flue gases. While in the laboratory most workers use dense polymeric films, asymmetric flat sheet membranes are used in industrial spiral-wound modules to maximize the plant productivity. These asymmetric membranes contain a very thin active layer and often exhibit very different permeation behavior compared to dense films. Water vapor, often a minor component in gas separation membrane systems, can hardly be avoided in industrial gas streams. It exhibits very different permeation behavior compared to other gas species because of its high hydrogen bonding affinity. The presence of water vapor is not always desirable in membrane gas separation systems as it often lowers the overall performance of the membrane due to plasticization and/or competitive sorption. In this thesis, the water vapor permeation behavior in two polyimide films (2,2’-bis(3,4’-dicarboxyphenyl) hexafluoropropane dianhydrid-2,3,5,6-tetramethyl-1,4-phenylenediamine (6FDA-TMPDA) and poly(3,3’-4, 4’-benzophenone tetracarboxylic - dianhydride diaminophenylindane) (Matrimid® 5218) has been studied under mixed gas/water vapour feed streams (CH4, CO2 and H2O) at 2 and 7.5 bar, 35 °C. Water vapor permeability was found to increase with water vapor activity for both polyimides. A decrease in permeabilities of both CH4 and CO2 for both pressures was also observed as water vapor was added for both polyimides. This loss in permeability can be related to competitive sorption effects. Mathematical models have also been developed to fundamentally understand the effect of the presence of water vapor in membrane separation units using polyimide membranes in a water vapor-gas multi-component system. These models predicted a decrease in diffusion coefficients, reflecting a reduction in fractional free volume caused by pore-filling effects. Pore filling by water molecules or clusters affected the diffusional pathway for both penetrating vapor and gas molecules. This was further verified by results from positron annihilation lifetime spectroscopy (PALS) measurements which showed reductions in microvoid numbers and size for both polyimides in the presence of water vapor. Overall, the trend of increasing water vapor permeability for both polyimides could be attributed to a combination of increasing vapor solubility and decreasing vapor diffusivity as water vapor activity increased. In addition, water vapor transport characteristics and membrane performance in the presence of water vapor have been investigated for flat-sheet Matrimid membranes of different thickness at 7.5 bar, 35 °C. The fractional free volume of Matrimid films in a wide range of thicknesses was found to decrease with decreasing film thickness. Solubility of water vapor was found to be…

▼ CO₂ Enhanced Oil Recovery (EOR) is a process that involves injecting large volumes of carbon dioxide as a supercritical fluid into hydrocarbon reservoirs in order to recover hydrocarbons that are not mobilized during primary or secondary production. Some of the injected CO₂ is produced with the produced hydrocarbons and then recycled by reinjection into the reservoir. Most CO₂ floods performed for EOR are miscible, which means the fluids mix to form a homogeneous mixture under a specific set of conditions. For a typical oil field, miscible floods are more efficient in recovering oil than immiscible floods. When recycled CO₂ includes a high percentage of methane, miscibility is significantly reduced. For a typical oil field, miscible floods are more efficient in recovering oil than immiscible floods. Calculations from produced fluid data base shows that at 18 mole percent methane, 28 percent of offshore oil reservoirs became immiscible (Ogbaubau, 2015). The effect was more pronounced in nearshore fields. In this study, I assessed the fluid distribution in a study area to determine if methane production can be avoided by strategic completion of wells to avoid high methane areas. High Island 10L, High Island 24L and ST TR 60S were selected due to availability of structural data. Using seismic, well log interpretation, and production data it was found that, of the wells evaluated, 94 percent had solution gas drive. A number of economic solutions to the problem were postulated; these included a methane separation facility, changes to CO₂ recycling, cutting CO₂ with another gas, and accepting immiscible flood conditions. The following equation was developed to estimate the increased cost for miscible CO₂ enhanced oil recovery: General Additional Costs of CO₂ Enhanced Oil Recovery = (Cost of CO₂ Recycling Plant + Cost of Pipelines + Cost of CO₂ to Offset Methane Immiscibility + Transportation costs + O&M costs + Pipeline Operation Costs) - (Value of Storage Tax Credit), Where: Cost of CO₂ to Offset Methane Immiscibility = (cost of CO₂/ton * tons of CO₂ needed to offset Methane), Cost of Pipelines= (cost of pipeline construction per mile * mumber of miles), Value of Storage Tax Credit = ($35/ton of CO₂ stored Tax Credit*tons of stored CO₂). The equations parameters were then used to create a table showing how the economic solutions might affect the cost of CO₂ enhanced oil recovery. Advisors/Committee Members: Hovorka, Susan D.

▼ While the injection of CO2 has great potential for increasing oil production, this potential is limited by site conditions and operational constraints such as the lack of proper infrastructure, limited cheap CO2 sources, viscous fingering, gravity override at the targeted zones, and others. The alternative methodologies which can successfully deliver CO2 through gas generation in situ, with superior improved oil recovery (IOR) performance, while offering reasonable chemical cost is explored to mitigate some of these common limitations. In this study, the ammonium carbamate and urea are considered as the new compounds capable of generating CO2 in situ. Their self-reaction ignition properties make the single fluid injection possible and reduce the complexity of the injection system. With exceptional water solubility (up to 40 wt.% for ammonium carbamate and 50% for urea at room temperature), ammonium carbamate and urea can be thermally endothermically hydrolyzed to CO2 and NH3 after equilibration under reservoir conditions. Because of their CO2 producing capacity and reasonable cost-benefit, they appear to be a promising candidate for delivering CO2 to increase oil recovery. In this work, the performance of injected aqueous chemical solutions was evaluated in a series of bench experiments to mimic tertiary oil recovery (perform test after the residual oil saturation was established by water flooding). One-dimensional sand pack tests and core flooding experiments were operated at different pre-set conditions: the flow rate varied from 0.03 to 0.3 ml/min, CO2 generating chemical concentrations from 1 to 35 wt%, pressures from 0 to 4000 psig, , temperature from 80 to 133℃ and different API gravity oils were used, varying from 27 to 57.3. The eluted crude oil and brine samples from these tests were collected and analyzed to assess the change of oil properties and brine chemistry influenced by the thermally produced CO2 and NH3. In addition, the reaction rates of urea hydrolysis were tested separately using a microwave reactor to compare the kinetics of urea hydrolysis reactions via varying reaction temperatures. Most importantly, results of injecting chemical solution (as low as 1 % solution) showed tertiary recovery performance (as high as 50%) as compared to the similar in situ CO2 generation EOR(2.4% to 18.8%) approaches proposed by others. Because of the reservoir brine compatibility of urea, even under high levels of divalent ions( Ca+2 7000 ppm), the experiment showed no detectable effect of brine composition on the recovery and/or any occurrence of formation damage. The post-reacted solution showed a solution pH about 10 because of the formation of NH3 (and NH4OH). Compositional analyses of the eluted oil also revealed different trends as compared to typical CO2 flooding, indicating additional benefits of this new CO2 delivery method resulted from the produced ammonia and its impact on the wettability of the solid surfaces. The economic feasibility and operational advantages of this newly developed method… Advisors/Committee Members: Shiau, Bor-Jier (Ben) (advisor), Harwell, Jeffrey (committee member), Wu, Xingru (committee member), Jamili, Ahmad (committee member), Moghanloo, Rouzbeh Ghanbarnezhad (committee member).

▼ The thesis presents observations on the CO2 mixing ratio and the carbon isotopic ratio (13C/12C i.e. δ13) of atmospheric CO2 from the Indian region, for the period 2008 - 2011. An experimental system was established at the Centre for Earth Sciences, Indian Institute of Science, Bangalore. The experimental protocol involves collection of air samples, extraction of CO2 from the air samples collected, and finally the measurement of the CO2 mixing ratio and isotopic ratios of the extracted CO2 using pressure gauge readings and the dual inlet peripheral of the isotope ratio mass spectrometer, IRMS MAT 253. The isotopic ratios measured are scaled to VPDB and corrected for their N2O contribution. The experimental set up is calibrated with primary carbonate standards (NBS19) and an air CO2 reference mixture. The analytical precision (reproducibility of paired samples) obtained for the atmospheric CO2 measurement is ±7 µ mol.mol-1, ±0.05‰ and ±0.17‰ for the mixing ratio, δ 13C and δ 18Oof atmospheric CO2 respectively. The present study lays emphasis on the CO2 mixing ratio and the δ 13C of atmospheric CO2. There are very few atmospheric CO2 monitoring stations in India. There exists only one long-term monitoring station, Cabo de Rama, on the west coast of India. Of late, a few new stations for measuring atmospheric trace gases have been in operation, with the major focus being on remote locations. Urban stations in India have never been monitored before for both the mixing ratio and the δ13C of atmospheric CO2 together. Monitoring urban stations in India is crucial today as they have become prime emitters of CO2 due to industrial activity. The emission from the sources varies seasonally and is influenced by factors like the Indian monsoon. The Indian subcontinent is surrounded by the Arabian Sea, the Indian Ocean and the Bay of Bengal which act differentially in terms of CO2 uptake or release. There is also a differential transport of CO2 to and from the open ocean. Thus, understanding the spatial pattern of CO2 in the marine region close to the Indian subcontinent is essential to understand the oceanic uptake/release of CO2. As part of this thesis, an urban area was monitored during 2008 - 2011 and the marine region was observed during the southwest monsoon of 2009. The temporal variation of the CO2 mixing ratio and δ13C of atmospheric CO2 was observed over an urban station, Bangalore (12° 58′ N, 77° 38′ E, masl= 920 m), India. Since Bangalore is one of the developing urban cities in India, it is interesting to monitor Bangalore air to understand the impact of anthropogenic emissions on atmospheric CO2 variability. The region has four distinct seasons, dry summer (March – May), southwest monsoon (June – September), post monsoon (October – November) and winter (December – February). Thus, it is also an ideal location to identify the effect of different seasons on the contribution of CO2 from various sources. Air samples were collected from the Indian Institute of Science campus, Bangalore, during 2008 - 2011. Both the… Advisors/Committee Members: Ghosh, Prosenjit (advisor).

▼ Nitrogenases are complex metalloenzymes capable of catalyzing two of the most challenging reactions in Nature: the reduction of atmospheric dinitrogen to ammonia and the reduction of carbon monoxide (CO) to hydrocarbons. The Azotobacter vinelandii molybdenum (Mo) and vanadium (V)-nitrogenases are homologous systems consisting of two components: the reductase component (Fe protein) and the catalytic component (MoFe or VFe protein, respectively). The reductase component contains a [Fe4S4]-cluster, whereas the catalytic component contains two unique metal clusters, the P-cluster and the M or V cluster for Mo- and V-nitrogenase, respectively. This dissertation focuses on the conversion of small carbon compounds such as the toxic exhaust CO and the greenhouse gas carbon dioxide (CO2) by nitrogenase proteins. The CO2 reducing capability of Mo- and V-nitrogenase was investigated under physiologically relevant assay conditions. Indeed, both nitrogenases reduce CO2 to CO, but only V nitrogenase reduces CO2 to hydrocarbons. These studies demonstrated that V-nitrogenase directly couples CO2 or CO2-derived species to hydrocarbon chains. Building on this, the efficiency of this reaction was improved by using the strong reductant europium(II) diethylenetriaminepentaacetate, rendering the ATP-dependent electron transfer obsolete and increasing the hydrocarbon chain length as well as the yield. Excitingly, the reductase component of V- and Mo-nitrogenase alone can reduce CO2 to CO. Strikingly, the reverse reaction, the oxidation of CO to CO2, is catalyzed under oxidizing conditions by Fe protein. The interconversion of CO and CO2 establishes the reductase component housing a [Fe4S4]-cluster as simple Fe/S-based mimic of CO dehydrogenase. The physiological relevance of this reduction is suggested by the observation that A. vinelandii strains expressing only the Fe protein component form CO2-derived CO in vivo.These discoveries led to the question of whether V-nitrogenase expressing A. vinelandii strains could also in vivo form hydrocarbons from CO or CO2. Indeed, this strain can convert CO to hydrocarbons in vivo. Furthermore, this process is a secondary metabolism since the carbon from CO is not incorporated into the cell mass, but released. Coupling the two in vivo processes could result in a biofuel process that catalytically converts CO2 into combustible hydrocarbon fuels.
