Summary: Two CO2 chemical absorption systems using AMP and MEA aqueous solutions were compared in terms of absorption performance and electrical properties. The study found that the absorption capacity in the AMP system increases linearly with C-ini, while the absorption rate in the MEA system is affected by concentration and primary reaction changes. The differences in performance can be attributed to the molecular structures and sizes of the two systems.

Summary: Integrated CO2 capture and utilization (ICCU) is an innovative strategy for large-scale CO2 emission reduction. This study focuses on the design of robust dual-function materials (DFMs) and the optimization of operating parameters for the ICCU process. The results showed that Ni loading has a significant impact on the structure-reactivity relationships of Ni-CaO DFMs pellets. The study also investigated the influence of operating parameters on CO2 capture capacity and CO2 conversion performance. The optimal operating conditions were determined, and the performance of the DFMs pellets was evaluated.

Summary: This study confirms the feasibility of CO2 geological sequestration in shale gas reservoirs through simulation analysis, while also revealing the impact of different CO2 injection schemes on reservoir performance and the sensitivity of permeability between hydraulic fractures. The results suggest the need for a well-designed execution plan and the implementation of efficient fracking to meet the demands for both CO2 sequestration and EGR in shale gas reservoirs.

Summary: In this study, glycol ether-functionalized imidazolium, phosphonium, and ammonium ionic liquids containing acetate (OAc-) or Tf2N- anions were designed. These task-specific ILs were found to have the capability to solubilize up to 0.55 mol CO2 per mole of IL (or 5.9 wt% CO2) at room temperature and atmospheric pressure. While acetate anions provided better CO2 capture, Tf2N- anions were more compatible with alcohol dehydrogenase (ADH), a key enzyme involved in the enzymatic conversion of CO2 to methanol. These promising results suggest the possibility of capturing and enzymatically converting CO2 under ambient pressure.

Summary: CH4/CO2 mixed hydrates can be dissociated effectively using the multistep cyclic depressurization method, leading to improved CH4 recovery below the stability pressure of CH4 hydrate. The study also highlights the impact of chemicals in the aqueous phase and reservoir temperature on recovery and storage yield. Additionally, the morphology study demonstrates the expansion of hydrate volume during cyclic depressurization, confirming hydrate reformation from released water from dissociation.

Summary: A COF-SILM was prepared for CO2/N-2 separation and showed ultra-high CO2 permeability and better CO2 selectivity compared to N-2. The outstanding performance is attributed to the ultrathin membrane, high-density pores, high transmembrane driving force, as well as the different adsorption capabilities of ionic liquid for CO2 and N-2, and a gating effect that allows CO2 passage while inhibiting N-2 passage.

Summary: This study investigates the absorption of diluted CO2 in carbonated NaOH solutions as a replacement for the conventional ammonia-soda process. By refitting the parameters, the average error was reduced and the mass transfer coefficient was evaluated for process design. The effects of NaOH and Na2CO3 concentrations and temperature on the mass transfer coefficient were studied.

Summary: In this research, artificial neural networks (ANN) and response surface methodology (RSM) were applied to model and optimize carbon dioxide (CO2) absorption using the KOH-Pz-CO2 system. The RSM approach utilized a central composite design (CCD) and multivariate regressions to fit second-order equations to the experimental data. The ANN method was further used as a global substitute model in optimization problems, providing more information about the quality of the acquired solutions.

Summary: By adding molten salt modifiers, the CO2 uptake of MgO-based CO2 adsorbents can be increased, with three different processes identified for the interaction of molten salt-promoted MgO with CO2 at 300 degrees C. Transient kinetic studies coupled with mass spectrometry provided a thorough understanding of the CO2-capturing performance and its significant implications for future practical designs of precombustion CO2 capture.

Summary: CO2-Binding organic liquids (CO(2)BOLs) are non-aqueous solvents that can reduce the energy consumption of carbon capture processes. These solvents exhibit surprising mass transfer behavior, with the flux of CO2 into CO(2)BOLs decreasing exponentially with increasing temperature. This phenomenon is primarily driven by a shift in reaction equilibrium, reducing the enhancement of CO2 flux by chemical reactions. First-principles surface renewal models accurately replicate the mass transfer data for CO2 absorption into different CO(2)BOLs, and density functional theory calculations identify structural modifications that could improve CO2 flux.

Summary: The study found that two imidazolium ionic liquids with very long alkyl chains perform better in CO2 capture but inferior in CH4 capture. These two ionic liquids also have higher CO2/CH4 selectivities. Molecular dynamics simulations showed that the aggregation of cations affects the accommodation space of CO2 and CH4 in the ionic liquids.
