摘要：
Selective methanation of CO in the reformate gas (CO/CO2/H-2/H2O = 0.175/17.9/70.9/11.1) proceeded over Ru catalysts supported on metal oxides and zeolites. CO was selectively methanated at wide temperature ranges (200-275 A degrees C) over Ru/gamma-Al2O3, Ru/TiO2 Ru/H-Y and Ru/H-beta catalysts. Higher Ru contents in Ru/gamma-Al2O3 improved the selective CO methanation rate.
