Abstract

A method is suggested to produce methane by contacting hydrogen with at least one of carbon oxides, taken in the amount of 0.1 to 10 mol.%, at a temperature of 120-450C, pressure of 1-203 atm and space velocity of 500-100000 hr-1 in the presence of catalyst. In order to increase productivity, titanium-iron alloy with Ti to Fe molar ratio ranging from 0.5:1 to 3:1 is used as the catalyst. Carbon monoxide, carbon dioxide or their mixture having molar ration CO:CO2 = 2.5:2.4 are used as the carbon oxide.
