Catalytic reactions of carbon monoxide with hydrogen have been studied in which intermetallic compounds of the formula MNi/sub 5/(where M is thorium, uranium, or zirconium) have been used as the catalysts. The materials perform effectively as methanation catalysts; ThNi/sub 5/ has a specific activity exceeding that of a typical commercial oxide-supported methanation catalyst by a factor of about 5. This material also shows superior resistance to hydrogen sulfide poisoning. Nickel, formed as a decomposition product of the MNi/sub 5/ intermetallic compound, is probably the active species, but its properties are influenced by the nature of M in the precursor MNi/sub 5/ system.
