Nickel-based Methane Production Catalyst (DZC-JWH42) Carbon Dioxide Hydrogenation to Methane-Other Catalysts-

Nickel-based Methane Production Catalyst (DZC-JWH42) Carbon Dioxide Hydrogenation to Methane

DZC-JWH42 is a methanation catalyst with higher content of nickel on aluminium support, which is used in the process of methane production,converting CO2 and H2 in syngas, into CH4.
The reaction is summarized as below:
CO2+4H2 ⇌ CH4 + 2H2O
