The CO hydrogenation activity of a Ru/Fe/TiO2 catalyst with reactant gases containing H2O was investigated for application in the production of substitute natural gas containing CH4 as the major component and C2–C4 hydrocarbons as the minor components. The total higher heating value (HHV) of the C1–C4 hydrocarbon products in the complete CO conversion was higher than 45 MJ/m3(Normal) for the CO hydrogenation using reactant gases containing H2O. Moreover, the HHV of the C1–C4 hydrocarbon products in the complete CO conversion was higher than 45 MJ/m3(N) over a wider temperature range when the H2/CO molar ratio in the reactant gas was 2.5 rather than when it was 3.0.
