Abstract
A carbonaceous material is converted to a fuel gas which is fungible with natural gas by a combination of steps comprising gasifying the carbonaceous material in the presence of air and carbon dioxide, purifying the effluent stream and separating carbon monoxide therefrom, catalytically reacting steam with the separated carbon monoxide and recovering a methane-rich product gas.
