Summary: Mitigating CO2 emissions from industries and other sectors of our economy is crucial for building a sustainable economy. This paper investigates different methanol synthesis routes based on CO2 utilization and compares them with the conventional methanol production using natural gas. The results show that using CO2 capture and utilization and tri-reforming of methane pathways can significantly reduce greenhouse gas emissions. However, the cost of methanol production via CO2 hydrogenation is three times higher than the conventional process. The tri-reforming process can be a more cost-effective option, but still requires financial support.

Summary: In this study, a series of In2O3-Al2O3 samples were prepared using flame spray pyrolysis, and the promoting role of Al in In2O3 was investigated. It was found that Al doping can enhance the methanol yield by increasing oxygen vacancies for CO2 adsorption and methanol formation. Additionally, small Al2O3 domains formed on the In2O3 surface contribute to higher CO selectivity by blocking active sites for CO2 hydrogenation.

Summary: This study investigates the promotion of Ni on In2O3 and optimization of NiO-In2O3 catalyst for CO2 hydrogenation. Ni facilitates the synthesis of CH3OH by reducing the dissociation barrier of H2, leading to reduced activation energy for CO2 hydrogenation. The interaction between Ni cations and In2O3 at low NiO loading enhances the surface density of oxygen vacancy, promoting the hydrogenation of adsorbed CO2 on O-v.

Summary: This study investigates the increase in ethylene production through the oxidative coupling of methane (OCM) process and the oxidative dehydrogenation of ethane (ODHE) as a supplemental process in a consecutive reactor media. The proposed configuration improves operative conditions and enhances ethylene production in consecutive reactors. The study analyzes the effects of reactant ratio, temperature, and pressure on conversions, product yields, and selectivities. The results show that increasing the CH4/O2 ratio decreases ethylene yield, while increasing contact time improves ethane conversion rate.

Summary: In this study, the solubilities of carbon dioxide in a DES composed of 1 NaBr + 6 ethylene glycol were experimentally measured at different temperatures and pressures. The measured data were used to optimize the fitting parameters of the Cubic Plus Association and the Soave-Redlich-Kwong equations of state. The results showed that both models provided reliable estimations, with the CPA EoS requiring smaller binary interaction parameters compared to the SRK EoS. The study also calculated thermodynamic properties and found that the interactions between carbon dioxide and the DES resulted in the release of energy and reduced disorder.
