Selective methanation of CO in reformed gas was carried out over Ru catalysts supported on various metal oxides and their catalytic performances were compared with the commercial Ru catalyst. Among the catalysts tested in this study, the operating temperature regions of Ru catalysts supported on alumina, titania and Y and beta zeolites were wider than that of commercial Ru catalyst. We supposed the support effects from the examination of the influence of gas composition and some characterizations.
