ABSTRACT:
In the production of a gas having a high calorific value and containing more than about 50% methane by volume by a process comprising gasifying a solid fuel under a pressure of about 5 - 150 bars by a treatment with oxygen and water vapor to produce a water vapor-containing raw gas at a temperature of about 350.degree.- 700.degree. C, the improvement which comprises further reacting the water vapor-containing raw gas under a pressure of about 5 - 150 bars with oxygen in a succeeding reactor to produce an intermediate product gas which contains mainly hydrogen, carbon dioxides, and methane and which leaves the reactor at a temperature between about 600.degree. and 950.degree. C, cooling the intermediate product gas and freeing the intermediate product gas from sulfur compounds. A dust fuel and/or liquid hydrocarbon can be added to the raw gas as such or after prereaction with oxygen, the addition advantageously taking place in the succeeding reactor. The reactor may contain a granular bed of a catalyst such as nickel, cobalt or chromium oxide and/or sulfide, and/or a contact material or catalyst support such as an oxide, spinel or silicate of aluminum and/or magnesium. The bed can be fluidized or otherwise mechanically moved.
