Process for the production of an intermediate Btu gas
An intermediate Btu gas is produced by reacting steam with a carbonaceous feed material in the presence of a carbon--alkali metal catalyst and substantially equilibrium quantities of added hydrogen and carbon monoxide at a temperature between about 1000/sup 0/ and about 1500/sup 0/F and a pressure in excess of about 100 psia to produce a raw product gas consisting essentially of equilibrium quantities, at reaction temperature and pressure, of methane, steam, carbon dioxide, carbon monoxide and hydrogen; withdrawing the raw product gas from the gasifier and treating it for the removal of acid gases to produce a treated gas; withdrawing a portion of the treated gas as an intermediate Btu product gas; mixing the remainder of the treated gas with steam; passing the resultant mixture into a steam reforming furnace where the methane in the gas reacts with the steam to produce additional amounts of carbon monoxide and hydrogen; and passing the effluent from the reforming furnace into the gasifier.
