Co2 hydrogenation over carbide catalysts
WebFurthermore, production of a large amount of CO2 (instead of water) and a high paraffin/olefin ratio reflected high activities of these catalysts for the water-gas shift reaction and hydrogenation, respectively. The high water-gas shift reaction activity allowed a CO-rich synthesis gas to be used efficiently over Mo-based catalysts. WebThe production of chemicals and fuels via chemical reduction of CO 2 by green H 2 represents a promising means of mitigating CO 2 emissions. The heterogeneous catalytic reaction of CO 2 and H 2 under atmospheric pressure primarily produces CO and CH 4, while CH 3 OH and C 2+ hydrocarbons are obtained at high pressure. Improving the …
