This is realized by a ceria-zirconia-based composite oxide having a chemical composition, by mass ratio, of zirconia: 30% to 80%, a total of oxides of one or more elements selected from yttrium and rare earth elements having atomic number 57 to 71 (except cerium and promethium): 0% to 20%, and a balance of ceria and unavoidable impurities, in which ceria-zirconia-based composite oxide, the composite oxide is deemed to be a single solid-solution phase in an X-ray diffraction pattern after a durability test which heats the oxide in the atmosphere at a temperature condition of 1100° C. for 5 hours and has a ratio (b/a) of mode pore diameter (b) of a pore distribution after a durability test which heats the oxide in the atmosphere at a temperature condition of 1100° C. for 5 hours to the mode pore diameter (a) before the durability test of 1.0≤b/a≤2.0 and/or has a ratio (d/c) of pore volume (d) after a durability test which heats the oxide in the atmosphere at a temperature condition of 1100° C. for 5 hours to the pore volume (c) before the durability test of 0.20≤d/c≤1.00.

摘要： Disclosed is a catalyst for methanation reaction producing methane with high conversion by reaction of hydrogen with carbon dioxide, or a gas mixture of carbon dioxide and carbon monoxide, or a gas mixture containing these compounds as the main components. The catalyst is prepared by the steps of mixing (A) aqueous zirconia sol with salts of (B) stabilizing element(s), which is selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Ca and Mg, and (C) iron group element(s), drying and calcining the mixture to obtain a catalyst precursor, and subsequent reduction of the precursor. The catalyst comprises, by atomic %, A: 18-70%, B: 1-20% and C: 25-80% based on the elemental states of the metals. The catalyst is characterized by multiple oxide of tetragonal zirconia structure, in which not only the stabilizing element(s) but also a part of the iron group element(s) is incorporated, and on which the iron group element(s) in the metallic state is supported.
