New metal complexes containing a methyldopa Schiff base for carbon dioxide storage

The high concentration of carbon dioxide in the environment, including from the burning of fossil fuels to meet our energy requirements, is a pressing environmental concern that requires urgent attention. As a result, the development of novel materials for storing gases such as carbon dioxide and hydrogen has garnered greater attention in research. The current work reports the synthesis of a Schiff base derived from methyldopa and its metal complexes. In addition, their effectiveness as carbon dioxide storage materials were assessed. The reaction of methyldopa and 4-hydroxybenzaldehyde in boiling ethanol under acidic conditions for four hours gave the corresponding Schiff base in excellent yield. The reaction of metal (copper, cobalt, and nickel) chlorides and Schiff base in boiling ethanol for three hours gave the corresponding metal complexes in high yields (77–83%). The surface morphology and surface area of the synthesized metal complexes were evaluated. The mesoporous complexes have a surface area that ranges from 3.59 to 7.36 m2/g. The average pores diameter was 7.75–12.27 nm, and the pores volume was 0.0.11–0.014 cm3/g. The carbon dioxide storage capacity of the synthesized mesoporous complexes was 27.4–30.6 cm3/gm. The complex containing nickel was the most efficient towards carbon dioxide uptake (30.6 cm3/cm) possibility due to its relatively high surface area (7.36 cm2/g) and pores volume (0.014 cm3/g) compared to the copper and cobalt complexes.

A thermophilic chemolithoautotrophic bacterial consortium suggests a mutual relationship between bacteria in extreme oligotrophic environments

A thermophilic, chemolithoautotrophic, and aerobic microbial consortium (termed carbonitroflex) growing in a nutrient-poor medium and an atmosphere containing N2, O2, CO2, and CO is investigated as a model to expand our understanding of extreme biological systems. Here we show that the consortium is dominated by Carbonactinospora thermoautotrophica (strain StC), followed by Sphaerobacter thermophilus, Chelatococcus spp., and Geobacillus spp. Metagenomic analysis of the consortium reveals a mutual relationship among bacteria, with C. thermoautotrophica StC exhibiting carboxydotrophy and carbon-dioxide storage capacity. C. thermoautotrophica StC, Chelatococcus spp., and S. thermophilus harbor genes encoding CO dehydrogenase and formate oxidase. No pure cultures were obtained under the original growth conditions, indicating that a tightly regulated interactive metabolism might be required for group survival and growth in this extreme oligotrophic system. The breadwinner hypothesis is proposed to explain the metabolic flux model and highlight the vital role of C. thermoautotrophica StC (the sole keystone species and primary carbon producer) in the survival of all consortium members. Our data may contribute to the investigation of complex interactions in extreme environments, exemplifying the interconnections and dependency within microbial communities.

Experimental and modelling studies of carbon dioxide capture onto pristine, nitrogen-doped, and activated ordered mesoporous carbons.

The search for suitable materials for carbon dioxide capture and storage has attracted the attention of the scientific community in view of the increased global CO2 levels and its after-effects. Among the different materials under research, porous carbons and their doped analogues are extensively debated for their ability to store carbon dioxide at high pressures. The present paper examined high-pressure carbon dioxide storage studies of 1-D hexagonal and 3-D cubic ordered mesoporous pristine and N-doped carbons prepared using the nano-casting method. Excess carbon dioxide sorption isotherms were obtained using the volumetric technique and were fitted using the Toth model. Various parameters that influence CO2 storage on metal-free ordered mesoporous carbons, such as the effect of pore size, pore dimension, pyrolysis temperature, the impact of nitrogen substitution, and the effect of ammonia activation are discussed. It was observed that the carbon dioxide storage capacity has an inverse relation to the total nitrogen doped, the amount of pyridinic nitrogen functionality, and the pyrolysis temperature, whereas the pore size seems to have a linear relationship. On the other hand, the presence of oxygen has a positive effect on the sorption capacity. Among the prepared ordered mesoporous carbons, the ammonia-treated one has shown the highest adsorption capacity of 37.8 mmol g-1 at 34 bar and 0 °C.

High storage capacity and high formation rate of carbon dioxide hydrates via super-hydrophobic fluorinated graphenes

Hydrate-based carbon dioxide sequestration technology has attracted widespread attention by promising potential in carbon neutralization process. However, the prerequisite of this technology requires fast CO2 hydrate formation kinetics with high gas absorption capacity. In this study, we compared the promotion effects of four kinds of graphite with different morphologies and hydrophobic properties on hydrate with the objective of identifying a mode for promoting the CO2 hydrate formation based on the properties of gas-liquid interface. The experimental results showed that fluorinated graphene with superhydrophobic nanostructure had the strongest gas storage effect by promoting hydrate nucleation and opening up channels for hydrate sustainable growth. When fluorinated graphene (FG-1) was sufficient to cover the interface sufficiently (1 wt%), the promotion effect was fully developed, resulting in a CO2 storage capacity of 3.53 mmol/g H2O. After combined with surfactant sodium dodecyl sulfate (SDS), 1 wt%FG-1+300 ppm SDS system achieved the best performance, making the gas storage capacity reach 5.02 mmol/g H2O. By observing the formation and decomposition process of hydrate, it was found that fluorinated graphene provided a hydrate formation platform, where the water below passed through the pores between FG-1 nanoparticles, and the gas above was adsorbed or diffused to hydrate formation sites. The modification of the interface by the fluorinated hydrophobic particles improved the solubility of CO2 in water, resulting in the formation of a large number of bubbles in the decomposition process. The special growth process in fluorinated graphene system made hydrate possess excellent CO2 storage performance, which was 1.24–7.56 times that of other nanomaterials. This mode of enhancing mass transfer at the gas-liquid interface provided a novel way to promote the development of hydrate-based applications. At the same time, this work was expected to provide new insights for the development of hydrate-based carbon sequestration technology.

Impact of injection temperature and formation slope on CO2 storage capacity and form in the Ordos Basin, China.

Carbon dioxide (CO2) storage capacity is the main criterion for assessing CO2 geological storage. Based on actual data from the Shiqianfeng formation in the Ordos Basin, three-dimensional (3D) models were built using the TOUGHVISUAL visualization software and simulated using the TOUGH2 integral finite difference modeling code with the ECO2N fluid property module to explore the impact of formation attributes (formation slope) and controllable factors (injection temperature) on CO2 storage capacity. A total of 16 schemes were designed, with four injection temperatures (24 ℃, 31 ℃, 38 ℃, and 45 ℃) and four formation slopes (0°, 5°, 10°, and 15°). Simulation results showed that the injection temperature and formation slope both had a significant influence on CO2 storage capacity. The impact of injection temperature on the total storage amount was more obvious than that of the impact of formation slope. A higher injection temperature resulted in a greater total storage amount. Increasing the formation slope and injection temperature increased the gas-phase, dissolved-phase, and total CO2 storage amounts in the upper left section of the injection well, but decreased them in the lower right part of the injection well. The impact of formation slope on the conversion rate from gas-phase CO2 to dissolved-phase CO2 was more obvious than the impact of injection temperature. A steeper formation slope resulted in a higher conversion rate. A smaller formation slope and a higher injection temperature should be selected to store CO2.

Assessment of Carbon Dioxide Storage Capacity of Selected Aquifers in ‘J’ Field, West Africa

combination of seismic data and petrophysical logs from five wells acquired in ‘J’ Field, Niger Delta, Nigeria, have been analyzed to assess the carbon dioxide (CO2) storage potential of some saline aquifers in ‘J’ field. The study aims to evaluate the volume of CO2 that can be potentially stored in the aquifers and the risk of CO2 leakages in the storage. The sand aquifers were correlated across the five wells to evaluate their thicknesses and lateral extent. Porosity, permeability, formation water resistivity, and net sand thickness were estimated in the different wells. The Horizons corresponding to the top of the aquifers was mapped, and time and depth structured maps were generated for structural analysis and volumetric estimations. The risk of CO2 leakages through sealing layers (cap rocks) was evaluated in terms of caprock integrity and pore pressure sealing mechanism. Results of the study showed that four aquifers, namely, L20, N30, M40, and P50, are laterally extensive across the five wells and have thicknesses that range from 14 to 352 m. The individual CO2 storage capacity of L20, M30, N40, and P50 was estimated to be 6.97×1010, 1.48×1010, 7.78×109 and 1.49×1010 tons, respectively. The combined aquifer storage capacity was estimated to be 1.07×1011 tons. The sealing layers have low risk of CO2 leakages. The study concluded that the aquifers have good potential for CO2 storage and low risk of leakages. The study ranked L20 as the best among the four aquifers.

Full coupling of CO2–CH4 transport and sorption with solid deformation in gas shale enhances natural gas recovery and geological CO2 storage capacity

A thermodynamically rigorous constitutive model is used to describe the full coupling among the nonlinear processes of transport, sorption, and solid deformation in organic shale where the pore fluid is the binary mixture of carbon dioxide and methane. The constitutive model is utilized in a numerical solution that simulates injection of carbon dioxide in shale before producing carbon dioxide and methane from the same. The solution considers advection and diffusion as viable mechanisms of pore fluid transport where the latter comprises molecular, Knudsen, and surface diffusion in ultralow permeability shale. Results indicate that gas adsorption would be the main storage mechanism of sequestration in shale which may comprise up to 70% of the stored CO2 mass. A third of this storage capacity could be due to the geomechanical effects. Therefore, complete or partial exclusion of the coupling between sorption and solid phase deformation from the solution would result in underestimation of carbon dioxide storage capacity and natural gas recovery factor of the rock. Surface diffusion, sorption-induced deformation, as well as strain-induced changes in gas sorption capacities, are all conducive to both outcomes. Sensitivity analysis shows that the solution results are most sensitive to changes in adsorption capacities, followed by initial permeability, Young's modulus, Poisson's ratio, surface diffusivities, and initial pore radius.

Utilization of depleted heavy oil reservoirs for carbon dioxide storage and sequestration: A molecular level assessment

Hydrocarbon-bearing formations have a life cycle that starts with initial development and ends with abandoning the formation once depleted. The number of abandoned reservoirs is increasing and is expected to do so over the foreseeable future. These reservoirs offer a sustainable solution to mitigate the negative impact of oil and gas industry on the environment. The abandoned reservoirs could serve as natural compartments to store greenhouse gasses, such as carbon dioxide, owing to their geological sealing features, the well-established understanding of their development, and the abundance of drilled wells that could serve as potential carbon dioxide injectors. Among other oil compounds, the abandoned oil phase is enriched with heavy oil components, such as asphaltene. The asphaltene deposition increases with an increased depletion rate and is mostly found as layers coating the rock grains. Owing to their molecular structure, asphaltene can host carbon dioxide in the sorbed form. In this study, realistic asphaltene structures are recreated on a molecular simulation platform and assessed for their carbon dioxide storage capacity. The findings substantiate asphaltene for its carbon dioxide storage capacity as absorbed (dissolved) and adsorbed phases. The presence of asphaltene increases the storage capacity of pore spaces by a factor up to 4 for the considered cases in this study. Furthermore, the sorption capacity has hysteresis favoring the retention of the sorbed phase. This study casts some light on the potential utilization of depleted heavy oil reservoirs for long-term carbon dioxide storage and sequestration.

Carbon Dioxide Captured on a Wet Si−C Composite Material with a Surfactant‐derived Carbon Film

AbstractThe storage capacity of carbon dioxide (CO2) on the wet SBA‐15 material can be greatly improved by forming gas hydrates. The presence of generous polar groups (hydroxyl groups) on the surface of SBA‐15 hinders the formation of CO2 hydrates. In order to further improve its CO2 adsorption capacity, the polar surfaces of SBA‐15 material are changed into non‐polar carbon surfaces by covering with carbon film, and Si−C composite is obtained. Compared with the SBA‐15 material, the pore size and pore volume of the Si−C composite material reduces but its morphology and structure are unchanged. Whether pre‐adsorbed water or not, the experiment results showed that the Si−C composite material is more conducive to the adsorption of CO2 than the SBA‐15 material. In a comparison of the Si−C composite material and the SBA‐15 material at 2.5 MPa, the CO2 adsorption capacity increased from 3.8 mmol/g to 8.5 mmol/g with dry samples, and the CO2 adsorption capacity increased from 20.1 mmol/g to 26.9 mmol/g with wet samples at Rw=2.0.

Modulating Carbon Dioxide Storage by Facile Synthesis of Nanoporous Pillared-Layered Metal-Organic Framework with Different Synthetic Routes.

A Zn(II)-based paddle wheel pillared-layered metal-organic framework, [Zn2 (DBrTPA)2(DABCO)].(DMF)2 (MUT-4), containing 1,4-diazabicyclo[2.2.2]octane (DABCO) and 2,5-dibromoterephthalic acid (DBrTPA) has been successfully synthesized with different synthetic methods, including solvothermal, sonochemical, and their mixing methods, some of which are energy-efficient, rapid, and room-temperature synthetic procedures. Structural characterization of MUT-4 with single-crystal X-ray crystallography showed that it crystallizes in the tetragonal I41/acd space group. MUT-4 has shown higher performance than known MOFs in the CO2 adsorption such as UiO-66, UiO-66-NH2, UiO-66-NO2, PCN-66, ZIF-68, UiO-67, bio-MOF-11, MIL-101, MOF-177, ZIF-8, and ZIF-82. It has shown even better CO2 adsorption performance in comparison to the previously reported DMOFs such as DMOF-1 and other DMOF analogues such as NO2-DMOF-1, NH2-DMOF-1, Br-DMOF-1, and Azo-DMOF-1. Furthermore, it has performed even better than modified known MOFs. Also, the carbon dioxide storage capacity of MUT-4 obtained using several different synthetic routes shows a significant difference. Thus, this study exhibited that CO2 gas adsorption of MUT-4 could be modulated by optimizing its synthetic methods.

A Laboratory Approach to Measure Enhanced Gas Recovery from a Tight Gas Reservoir during Supercritical Carbon Dioxide Injection

Supercritical carbon dioxide injection in tight reservoirs is an efficient and prominent enhanced gas recovery method, as it can be more mobilized in low-permeable reservoirs due to its molecular size. This paper aimed to perform a set of laboratory experiments to evaluate the impacts of permeability and water saturation on enhanced gas recovery, carbon dioxide storage capacity, and carbon dioxide content during supercritical carbon dioxide injection. It is observed that supercritical carbon dioxide provides a higher gas recovery increase after the gas depletion drive mechanism is carried out in low permeable core samples. This corresponds to the feasible mobilization of the supercritical carbon dioxide phase through smaller pores. The maximum gas recovery increase for core samples with 0.1 mD is about 22.5%, while gas recovery increase has lower values with the increase in permeability. It is about 19.8%, 15.3%, 12.1%, and 10.9% for core samples with 0.22, 0.36, 0.54, and 0.78 mD permeability, respectively. Moreover, higher water saturations would be a crucial factor in the gas recovery enhancement, especially in the final pore volume injection, as it can increase the supercritical carbon dioxide dissolving in water, leading to more displacement efficiency. The minimum carbon dioxide storage for 0.1 mD core samples is about 50%, while it is about 38% for tight core samples with the permeability of 0.78 mD. By decreasing water saturation from 0.65 to 0.15, less volume of supercritical carbon dioxide is involved in water, and therefore, carbon dioxide storage capacity increases. This is indicative of a proper gas displacement front in lower water saturation and higher gas recovery factor. The findings of this study can help for a better understanding of the gas production mechanism and crucial parameters that affect gas recovery from tight reservoirs.

Optimization of Cyclone-Type Rotary Kiln Reactor for Carbonation of BOF Slag

Mineral carbonation of the basic oxygen furnace (BOF) slag produced in the steel-making process not only provides an effective approach for carbon dioxide storage, but also stabilizes the slag such that it can be reused as a construction material. Generally speaking, carbonation performance improves as the time for which the carbon dioxide resides within the reactor increases. This research proposes a method to increase the residence time of carbon dioxide in the cyclone converter slag carbonization kiln by adjusting the inclination angle and length of the feed pipe. Therefore, it has the same effect of increasing the flow path length of the cyclone in the reactor. The optimal values of the inclination angle and length of the gas inlet tube are determined using the robust Taguchi design method. Computational fluid dynamics simulation results show that the optimized reactor design increases the average residence time of carbon dioxide gas by 60.4%, compared with the original rotating reactor design with a straight (non-cyclonic) flow path. Moreover, the experimental results show that the optimized design increases the carbon dioxide storage capacity from 12.15 g per kilogram of BOF slag in the original rotary kiln reactor to 16.00 g in the re-designed reactor.

Monte Carlo Molecular Simulation Study of Carbon Dioxide Sequestration into Dry and Wet Calcite Pores Containing Methane

We perform grand canonical Monte Carlo (GCMC) simulations to study the adsorption of carbon dioxide in a calcite slit pore. The injection of carbon dioxide is simulated by increasing the chemical potential of carbon dioxide, which allows for an investigation of adsorption under varying carbon dioxide loadings. The study is carried out for three different environments: an empty pore; a pore containing methane; and a pore containing methane with trace amounts of water. We systematically investigate the impact of the presence of these other fluids on carbon dioxide adsorption. We study the influence of carbon dioxide loading on fluid density in the pore and examine individual fluid-density profiles (in the direction normal to the fluid–solid interface). The order of fluid adsorption affinity to the surface is found to be water > carbon dioxide > methane. The interpretation of our results is informed by the examination of free-energy-averaged fluid–substrate potentials, which are computed independently from the simulations. Our observations suggest that ignoring the presence of water could lead to overestimation not only of methane availability but also of carbon dioxide storage capacity in pores, with important consequences in, for example, modeling carbon dioxide sequestration in calcite-rich reservoirs. Ultimately, it is hoped that the molecular-level insights from this study will aid the multiscale modeling of reservoir fluids in the context of enhanced oil recovery and carbon dioxide sequestration.

Assessment of Hydrate Formation, Storage Capacity, and Transport Properties of Methane and Carbon Dioxide through Functionalized Carbon Nanotube Membranes

The present work investigates the gas hydrates, storage, and transport properties of methane (CH4) and carbon dioxide (CO2) across carbon nanotubes (CNTs) designed by CONH2 (aquaporin, AQP selective filter), H2O2, and COOH functional groups via molecular dynamics (MD) simulations. Two separate systems of water–CH4 and water–CO2 at different mole fractions have been considered. The main goal is to discuss, for the first time, the gas hydrate formation mechanism in the membrane technology framework as a promising approach to mitigate the drawbacks in traditional hydrate technologies. Our model membranes offer very high CH4 storage capacity concerning available experiments. The hydrate cages decrease since the mole fraction increases (or water loading decreases), suggesting a significant contribution of water hydrogen-bonded in the hydrate formation process. The CNT-CONH2 and CNT-H2O2 model membranes provide higher hydrate cage numbers compared to CNT-COOH, suggesting a better performance for CNT-CONH2. The CNT-CONH2 shows a higher hydrate cage in the presence of CO2, particularly at the small mole fraction, while CNT-COOH and CNT-H2O2 are good at the large mole fraction. Regardless of the gas type (CH4 or CO2), both CNT-CONH2 and CNT-H2O2 model membranes suggest better performance in gas hydrate formation. Moreover, our simulated model membranes indicate better efficiency in the formation of gas hydrates concerning available experiments. An enhancement in hydrate formation in the presence of CH4 was also found in the CNT-CONH2 and CNT-H2O2 model membranes concerning the bulk system, suggesting a better performance for CNT-CONH2. This finding could reflect the potential of the membrane-based hydrate formation over the bulk system. The transport properties of water/CH4/CO2 across the model membranes have also been discussed.

Synthesis, structural characterization, and carbon dioxide and hydrogen adsorption of a new three-dimensional metal organic framework Zn(BTC)4

A novel three-dimensional porous metal organic framework Zn(BTC)4 (BTC = benzene-1,3,5-tricarboxylic acid) is synthesized by the solvothermal method. This structure is characterized by single-crystal X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis. This metal organic framework crystallizes in a monoclinic (P2(1)/n, V = 1795.7(2) Å3, Z = 4, Dc = 1.449 mg/cm3, α = 90.00°, β = 97.2200(10)°, γ = 90.00°, a = 9.5077(5) Å, b = 16.3950(16) Å, c = 11.6119(9) Å). The thermogravimetric analysis shows the material can be stabilized up to 350 °C, then the skeleton collapses between 350~510 °C. A luminescence test shows that the material gives out strong emission at 384 and 462 nm. The hydrogen storage capacity of this metal organic framework is 2.01 wt% at 77 K and a pressure of 10 bar. The carbon dioxide storage capacity of this metal organic framework is 4.17 mmol/g at 298 K and a pressure of 10 bar.

A laboratory approach on the improvement of oil recovery and carbon dioxide storage capacity improvement by cyclic carbon dioxide injection

This paper experimentally investigated influential thermodynamic reservoir characteristics such as pressure, temperature, soaking time, core stimulation, number of cycles, shale particle size, and carbon dioxide phase during the cycling carbon dioxide injection. The carbon dioxide supercritical phase has reached the maximum recovery factor of 40%. When carbon dioxide is in the supercritical phase, its density will become lower than the liquid phase due to the high pressure. Therefore, the oil recovery factor has been increased in micro and nanopores. It is concluded that more than 12 h of carbon dioxide soaking would not play a significant role in oil recovery enhancement. It was observed that each shale particle size distribution would be a proper representative for the carbon dioxide adsorption calculation. Therefore, by doing this, the required time to equilibrate pressure for carbon dioxide adsorption would be decreased by pulverizing the shale cores into micro and nanoparticles. In higher temperatures, carbon dioxide helps to retrograde vaporize hydrocarbon liquid as carbon dioxide provided a higher gas–oil ratio (GOR), higher value of condensate oil density. Thereby, due to increased carbon dioxide content, oil recovery has been increased, indicating that carbon dioxide would be properly soluble. Therefore, at 120 °C, the oil recovery factor has the highest value of 64%. At 3000 psi, the oil recovery factor has the highest value, and it has reached 60% after 14 cycles of carbon dioxide injection. It would be related to the more surface area of carbon dioxide with shale matrixes. Finally, temperature increase would reduce the carbon dioxide absorption, which has a reverse pattern with oil recovery factor increase by the temperature increase.

Evaluation of hygrothermal performance of wood-derived biocomposite with biochar in response to climate change

Wood is a sustainable resource and building material. It provides an excellent response to climate change and has excellent insulation performance. However, structural defects may occur due to decay from moisture, resulting in poor dimensional stability. The rich organic substances contained in wood can lead to mold when the moisture content is consistently high, adversely affecting the health of occupants. Therefore, we attempted to compensate for the disadvantages of wood in regard to water stability while maintaining the high thermal insulation performance and carbon dioxide storage capacity, using biochar from thermally decomposed spruce under oxygen limiting conditions. A wood-derived biocomposite was prepared by mixing biochar and soft wood-based chips using the hot-press method, and the thermal conductivity, specific heat, water vapor resistance factor, moisture adsorption, and moisture desorption performances were analyzed. The thermal conductivity of WB10 with 10 wt% biochar content was 0.09301 W/mK. This is a 7.98% decrease from 0.10108 W/mK, the thermal conductivity of WB0 without biochar. The water vapor resistance factor tended to increase when the biochar ratio increased. As the proportion of biochar increased, the equilibrium moisture content in high relative humidity tended to decrease, and it was found that the moisture adsorption and desorption performances were affected by the ratio of the biochar. Therefore, wood-derived biocomposites using biochar can be used in environmentally friendly materials, with improved thermal insulation performance and water stability.
