Studies of the methanation reaction by the U.S. Bureau of Mines, aimed at preparing SNG from raw, coal-derived synthesis gas, have tried a variety of catalysts and reactors, including fixed-bed, fluid-bed, hot gas recycle, and tube wall reactor (TWR) units. Nickel catalysts are more effective in yield, activity, and selectivity than iron catalysts, but are sensitive to sulfur poisoning and carbide formation. Thus far, flame-sprayed Raney nickel catalyst in the TWR system has given the best methanation results. Run TWR-6 successfully completed 2850 hours of operation for a product gas yield of 232,000 cu ft/lb catalyst. Comparative data are presented for a large number of catalysts.
