Gent, C W

A process for producing a substitute natural gas from methanol, especially seaborne methanol liable to be contaminated with chloride, comprises catalytically reacting methanol vapor in a decomposition stage at an outlet temperature above 550/sup 0/C, cooling the resulting gas by indirect heat exchange, preferably with water, to 250 to 350/sup 0/C, methanating the cooled gas with an outlet temperature of 500 to 650/sup 0/C, cooling the methanated gas by indirect heat exchange, preferably with methanol, and methanating the resulting gas in at least one further methanation stage. By avoiding the injection of liquid methanol, as had been previously proposed, for cooling the hot gas, the poisoning of catalysts by impurities such as chloride does not take place. 4 claims, 1 figure.
