ABSTRACT:
A high methane gas which can be substituted for natural gas is produced from a primary gas made by the gasification of coal, tar, or heavy residual oil under superatmospheric pressures. The primary gas is purified to remove catalyst poisons and is scrubbed to remove carbon dioxide to a residual content below 2% by volume. The water vapor to carbon monoxide volume ratio of the scrubbed gas is adjusted to 0.55 : 1 to 1 : 1 and is then passed through a reaction zone containing a shift conversion catalyst and a methanation catalyst in a volume ratio of approximately 1 : 4 to 1 : 10. The scrubbed gas entering the reaction zone enters the reaction zone at a temperature of 300.degree.-500.degree. C.
