Catalyst for methanation reaction, method for producing catalyst for methanation reaction, and method for producing methane

摘要

The methanation reaction catalyst is a methanation reaction catalyst for methanation by allowing CO and/or COto react with hydrogen, wherein the methanation reaction catalyst includes a stabilized zirconia support, into which a stabilizing element forms a solid solution, and having a crystal structure of a tetragonal system and/or a cubic system, and Ni supported on the stabilized zirconia support. The stabilizing element is a transition element of at least one selected from the group consisting of Mn, Fe, and Co.
