Promotion effect of heat and mass transfer characteristics on CO2 methanation over the structured Ni/CeO2 catalyst

摘要

The CO2 methanation is the hydrogenation of CO2 for production of CH4 in Eq.1. The CO2 methanation has also gained great attention in the aspect of CO2 utilization and hydrogen storage'. Fukuhara et ah have introduced the structured reaction system for CO2 methanation, enabling the process to operate at high gas feed rate with low pressure drop across the reactor. Furthermore, they reported that the structured Ni/CeO2 catalyst indicated a high methanation performance.
