Experiments were carried out on the use of a multiple catalyst system consisting of potassium carbonate and a commercial nickel methanation catalyst for the direct production of methane from coal-steam reactions. This system combines the effects of these catalysts to produce in a single-step conversion a product gas consisting primarily of methane and carbon dioxide with a CO/sub 2/-free heating value as high as 850 Btu per SCF. Two of the apparent problems inherent with such a system were catalyst recovery and the loss of catalyst activity over prolonged periods of time at the conversion temperatures in the presence of the various reactants produced from the coal gasification. In conjunction with the latter problems, experiments were also performed on the influence of sulfur compounds produced during gasification upon catalyst life and activity. (GRA)
