Several molybdenum compounds - oxides, sulfide, metal, carbide, and nitride - were prepared, and their catalytic properties in the hydrogenation of CO/sub 2/ at 350/sup 0/C were investigated and compared with those of nickel and iron. The initial specific activities, rates per unit surface area of catalyst, decreased in the sequence Ni > Mo carbide > Mo metal > Mo nitride > MoO/sub 2/ > MoS/sub 2/ > MoO/sub 3/. Iron deactivated so rapidly that its initial activity could not be determined. The molybdenum compounds produced very much smaller amounts of C/sub 2/ and C/sub 3/ hydrocarbons in the hydrogenation of CO/sub 2/ than in that of CO. Iron produced the largest amount of higher hydrocarbons from CO/sub 2/, and Ni only CH/sub 4/. The molybdenum compounds, except MoS/sub 2/ and MoO/sub 3/, had higher activities for water-gas-shift reaction.
