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.

摘要： A methane production system comprises: a reaction tank that produces methane and water by reacting CO and/or CO2 supplied to the reaction tank with hydrogen; a cleaning tank that is located at an upstream side of the reaction tank in a supply direction of the CO and/or CO2, and removes water-soluble impurities from a raw material gas including the CO and/or CO2 and the water-soluble impurities by bringing the raw material gas into contact with water; and a first supply line that supplies the raw material gas from which the water-soluble impurities are removed from the cleaning tank to the reaction tank; and a second supply line supplies water produced in the reaction tank from the reaction tank to the cleaning tank to bring the produced water into contact with the raw material gas in the cleaning tank.
