Abstract
Methane and carbon dioxide are produced by reacting steam with a carbonaceous feed material at a reaction temperature between about 1000.degree. F. and about 1500.degree. F. and a reaction pressure in excess of about 100 psia in the presence of a carbon-alkali metal catalyst and equilibrium quantities of added hydrogen and carbon monoxide. The raw product gas withdrawn from the reaction zone is treated for removal of the carbon dioxide, product methane is recovered from the treated gas, and the remaining hydrogen and carbon monoxide can be recycled to supply the added hydrogen and carbon monoxide needed in the reaction zone.
