PURPOSE:To obtain a hydrocarbon which is a high-octane gasoline fraction having excellent quality, selectively, in high yield with one-step process, by contacting a synthesis gas with a mixed catalyst composed of an Ru-supporting vanadium oxide and crystalline zeolite. CONSTITUTION:The objective compound is prepared by the catalytic reaction of synthesis gas, especially a mixture of CO and H2 in the presence of a catalytic composition composed of an Ru-supporting vanadium oxide and crystalline zeolite, at 150-450 deg.C and 5-200kg/cm<2> pressure at a GHSV (gas hourly space velocity) of 100-10,000 synthesis gas volume under standard temperature and pressure per unit volume of the catalyst per hour. The mixed catalyst can be prepared, e.g. by reducing V2O5 powder in H2 stream, immersing the obtained vanadium oxide in an aqueous solution containing a ruthenium compound such as ruthenium chloride to obtain an Ru-supporting vanadium oxide, and mixing the oxide with a crystalline zeolite having a pore diameter of 5-9Angstrom and a molar ratio of silica/alumina of >=12. |
