The CAMERE (Carbon Dioxide Hydrogenation to Form Methanol via a Reverse Water‐Gas Shift Reaction) process for the transformation of CO2 into methanol comprises reverse water‐gas shift (RWGS) and methanol production. In this work, the reaction kinetics of RWGS was investigated using a commercial Pt/Al2O3 catalyst. Catalytic runs were accomplished in a fixed‐bed flow reactor at 0.1 MPa in the 573–873 K range. The space time was varied in the 0.03–0.25 g · h/L range. The prevalence of the chemical control regime was established. The influence of reaction variables on the catalyst performance was investigated, and it was found that the increase in pressure resulted in a growing CO2 conversion value. The reactor was operated under differential reaction conditions and the influence of the H2/CO2 ratio in the feed on reaction rates was studied. Finally, the reaction pathway was analyzed using the associative and redox reaction mechanisms, and the latter appeared dominant over Pt/Al2O3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
