Van den Berg, G J; Ouwerschuur, F K.G.

A process for the production of synthetic natural gas or town gas is described wherein the hot gaseous product of the partial combustion of a carbonaceous fuel, containing hydrogen and carbon monoxide, is passed into a carburetting zone at a temperature of from 700 to 1100/sup 0/C and therein enriched with a volatile hydrocarbon carburant which on evaporation into the hot gaseous product of partial combustion is thermally cracked into methane and lighter unsaturated hydrocarbons. The carburetted gas product is then passed into a hydrogenation zone maintained at a temperature sufficient to further decompose any remaining hydrocarbon carburant and to hydrogenate the unsaturated hydrocarbons. In this process coke formation in the carburetting zone is substantially minimized by introducing the volatile hydrocarbon carburant into the carburetting zone in the form of a thin layer of liquid which is maintained at a temperature below that at which thermal cracking occurs during the time the carburant is not adsorbed by the hot gas steam.
