Abstract

A method is suggested to produce methane by the conversion of carbon monoxide at elevated temperature in the presence of heterogeneous catalyst. In order to increase the CO conversion and simplify the process technology, a hydride of zirconium-nickel or zirconium-cobalt alloy is used as the heterogeneous catalyst, containing (wt.%)

Zirconium 59-48
Nickel or cobalt 38-50
Hydrogen the rest

Otherwise, a hydride of hafnium-nickel or hafnium-cobalt alloy is used, containing (wt.%)

Hafnium 75-48
Nickel or cobalt 24-50
Hydrogen the rest

The process is carried out at 300-500C.
