Summary: Carbon capture and sequestration (CCS) has the potential to mitigate global climate change. Integrating a high temperature solid oxide electrolyzer (SOE) with the CO2 hydrogenation process can reduce the cost of methanol production. Further cost reduction in methanol production is possible with advancements in hydrogen production technology, such as high performance materials development and commercialization of electrolyzers.

Summary: The study examined the thermodynamic and economic feasibility of methanol synthesis from CO2 and H-2. Three reactions, CO2 hydrogenation to methanol, reverse-water-gas-shift (RWGS), and methanol decomposition, were investigated. The effects of temperature, pressure, and H-2/CO2 mole ratio on CO2 conversion and methanol selectivity were examined and compared to experimental data. A conceptual process design for methanol synthesis using Aspen Plus was developed. The techno-economic feasibility study revealed that the proposed process can be economically viable under certain conditions.

Summary: This study improves the process of producing propylene carbonate from CO2 and propylene oxide by using [P66614][Br] as a catalyst through an integrated experimental-computational approach. Experimental results show that the use of fatty alcohols as solvents can increase the yield of propylene carbonate and achieve the separation of ionic liquids and propylene carbonate, while water reduces the selectivity of propylene carbonate. By controlling the dosages of fatty alcohols and water, energy consumption, vacuum requirements, and operating costs can be minimized.

Summary: To achieve efficient utilization of CO2 and produce clean alternative fuel, CO2-to-DME (CTD) technology is considered a feasible and promising solution. In this study, four different CTD processes were proposed and compared in terms of technical and economic performance. Case 4 showed the highest energy efficiency (77.42%), exergy efficiency (88.46%), and net CO2 mitigation rate (67.71%) from a technical perspective. On the other hand, Case 2 had the lowest total product cost (1327.14 $/tonne DME), while Case 4 had the lowest net CO2 mitigation cost (589.34 $/tonne CO2). Improvement measures were also proposed for optimizing Case 4, resulting in increased net CO2 mitigation rate and decreased net CO2 mitigation cost.

Summary: Cr2O3 was used to modify In2O3 catalysts for CO2 hydrogenation to methanol reaction. Various characterization techniques were employed to analyze the structure of the catalysts, and the performance was evaluated in a fixed-bed reactor. The results demonstrated the formation of solid solutions and the crucial role of electronic interaction between Cr2O3 and In2O3 in the hydrogenation reaction. The In1.25Cr0.75O3 sample exhibited the highest methanol yield and showed no deactivation during the reaction. The improved catalytic performance can be attributed to the formation of solid solutions and the highest amount of oxygen vacancies.

Summary: This study investigates the efficiency of methanol synthesis via sorption enhanced carbon dioxide hydrogenation and determines the optimal process parameters using an experimentally validated model. The results indicate that for synthesis of high purity methanol product, the optimal values of reactor temperature and catalyst mass fraction in the bed are 215 degrees C/0.65 and 235 degrees C/0.50 for the adiabatic and quasi isothermal reactors, respectively. Additionally, a reactor configuration with a guard adsorbent layer is proposed for production of high purity methanol product.
