PROBLEM TO BE SOLVED: To provide a catalyst for producing C2+hydrocarbons from a mixed gas containing carbon dioxide and/or carbon monoxide and hydrogen in high yield.SOLUTION: There is provided a composite catalyst for synthesizing hydrocarbons having two or more carbon atoms from a mixed gas containing carbon dioxide and/or carbon monoxide and hydrogen, including a methanol synthesis catalyst and organic group-modified zeolite catalysts, in which the organic group-modified zeolite catalysts are composite catalysts obtained by reacting zeolite catalysts and an organic compound at a high temperature. There is also provided a composite catalyst in which the organic compound is at least one selected from an organosilane compound, an organoboron compound, an organoaluminum compound, an organotin compound, an organic oxygen-containing compound, an aromatic compound, a heteroaromatic compound and an aliphatic or alicyclic unsaturated compound.SELECTED DRAWING: Figure 2 |
