초록
The catalytic activity of CO2 methanation with H2 over M*/Mn/Cu–Al2O3 (M* = Pd, Rh and Ru) oxidecatalysts in simulated natural gas was investigated. Among them, Ru/Mn/Cu–Al2O3 catalyst was found tobe the most promising catalyst. Response surface methodology involving central composite design wasemployed and Ru loading was found to be the most significant effective factor, followed by calcinationtemperature and catalyst loading. The optimum condition for CO2 conversion was at 10.9 wt.% Ruloading, calcination temperature of 1035 8C and catalyst loading of 5 wt.g. Interestingly, the RMC10catalyst demonstrated good activity, stability and robustness during entire testing period which issuitable for industrial application.
