Enhanced low temperature reaction for the CO2 methanation over Ru promoted Cu/Mn on alumina support catalyst using double reactor system

The bimetallic copper with manganese (Cu/Mn) on alumina (Al2O3) support have been considered as potential catalyst for the carbon dioxide methanation due to the low cost and its unique ability to facilitate the conversion of carbon dioxide (CO2) to methane gas (CH4). However, high operating reaction...
