摘要：

Selective CO methanation has been investigated to remove CO contained in hydrocarbon reformates applicable to polymer electrolyte fuel cells. High selectivity of CO methanation is important, since excessive hydrogen consumption as well as runaway of methanation reaction can occur if CO2 methanation reaction proceeds simultaneously. In this study, selective CO methanation was investigated over supported ruthenium catalysts, and effects of supports and metal additives to ruthenium on the activity and selectivity of CO methanation were examined. Selectivity of CO methanation was improved over TiO2-supported Ru catalysts, compared to those supported on Al2O3. Nickel addition to Ru/TiO2 enhanced CO methanation activity, whereas CO2 methanation was not promoted, leading to the expansion of the temperature range for selective CO methanation.
