简介 A method for producing hydrocarbons, comprising : (I) subjecting to a reduction treatment a catalyst comprising a carrier having provided thereon : 0.1 to 10% by mass of at least one metal selected from an alkali metal, an alkaline earth metal, a rare earth metal and the Group III in the periodic table and 1 to 30% by mass of ruthenium, each based on the catalyst weight, the carrier comprising an aluminum oxide and a manganese oxide having an average number of charges of manganese of exceeding Mn2+, and the catalyst having a specific surface area of from 60 to 350 m2/g and a bulk density of from 0.8 to 1.8 g/ml; (II) dispersing the catalyst in liquid hydrocarbons in a concentration of from 1 to 50 w/v %; and (III) bringing the catalyst into contact with a gas mixture comprising hydrogen and carbon monoxide at a pressure of from 1 to 10 MPa, and (i) at a reaction temperature of from 170 to 300° C. under such conditions that carbon dioxide is substantially absent, or (ii) at a reaction temperature of from 200 to 350° C. under such conditions that carbon dioxide coexists in an amount of from 0.5 to 50% based on the total pressure of the hydrogen and the carbon monoxide.
