The initial specific activities of the unsupported catalysts tested for the reaction of 3:1 hydrogen/carbon monoxide at 350/sup 0/C decreased in the order nickel > molybdenum carbide > molybdenum > molybdenum nitride > molybdenum dioxide > molybdenum disulfide > molybdenum trioxide. The molybdenum carbide, which apparently acted as a catalyst and not an intermediate, was more stable than the other catalysts. The molybdenum metal produced more C/sub 2/-C/sub 3/ hydrocarbons than the sulfide or oxide. The molybdenum compounds except the sulfide and trioxide had higher activities for the water gas shift than nickel or iron and were as active in 1:1 as in 3:1 hydrogen/carbon monoxide conversion. The product distributions suggested that hydrogenation of carbon monoxide proceeds by different mechanisms on molybdenum and Group VIII metal catalyst.
