Abstract: Methane is produced by the thermoneutral reaction of steam with coal or other carbonaceous material in a hydrogasification zone containing an alkali metal catalyst and sufficient hydrogen to suppress competing endothermic reactions. The gas taken overhead from the gasifier is subjected to steam reforming and then processed for the removal of acid constituents, hydrogen which is recycled to the hydrogasification zone, and carbon monoxide which is used as fuel for the steam reformer.
