The effect of products on the reaction of 10% carbon monoxide in hydrogen on reduced CCI fused magnetite catalyst was studied by adding carbon dioxide, water, ethane, ethylene, or oxygen to the feed or replacing one reactant with the product. The addition of 5% CO/sub 2/ to the feed decreased methane production by 8%. The addition of 0.6% water to the feed inhibited hydrocarbon production considerably and only a part of the original hydrocarbon formation was regained when the water addition was discontinued. Replacement of hydrogen by 0.6% water in helium stopped all hydrocarbon formation and produced carbon dioxide at a high rate. Replacement of CO with ethane, ethylene, propylene, or butenes gave products that were mostly of shorter chain length than the reactant at rates which suggested that the rate-determining step in the CO methanation is the hydrogenation of active surface carbon (derived from the dissociative CO adsorption) and that the subsequent reaction steps of surface CH and CH/sub 2/ species are rapid. The results support the previously proposed mechanism.
