PURPOSE:To carry out the reaction for the preparation of hydrocarbon from methanol and/or dimethyl ether, by using a crystalline silicate compound as the catalyst having remarkably high activity and long life. CONSTITUTION:A hydrocarbon is prepared by the catalytic reaction of methanol, dimethyl ether, etc. at 250-600 deg.C and 0.8-20kg/cm<2> pressure using a catalyst composed mainly of a crystalline silicate compound containing the compound of formula (M is Ag, Zn, Sn, Ti, Sb, Co, Rh, or lantanide rare earth element; n is atomic valence of the element M; x is 1-5,000) as an essential component. The crystalline silicate compound can be obtained by reacting an SiO2 source (e.g. alkali metal silicate), chloride, etc. of the element M, and an inorganic alkali and/or a nitrogen-containing compound in an aqueous solution or dispersion at 100-250 deg.C, and crystallizing the product. The catalyst can be regenerated easily by calcining at 500-700 deg.C. |
