Abstract Selective CO methanation as a strategy for CO removal in micro fuel processing applications was investigated over Ru-based catalysts. Ru loading, pretreatment and reduction conditions, and choice of support were shown to affect catalyst activity, selectivity, and stability. Even operating at a gas-hourly-space-velocity as high as 13,500 hr-1, a 3%Ru/Al2O3 catalyst was able to lower CO in a reformate to less than 100 ppm over a wide temperature range from 240oC to 285 oC, while keeping hydrogen consumption below 10%.
