Abstract
A method for producing a hydrocarbon liquid fuel including hydrocracking a raw material oil in the presence of a hydrocracking catalyst, at a supplying pressure of hydrogen of from 0.1 to 1.0 MPa, a liquid space velocity of liquid volume of the raw material oil of from 0.05 to 10.0 hr−1, and a flow rate of the hydrogen from 50 to 3,000 NL per 1 L of the raw material oil, wherein the hydrocracking catalyst is produced by a method including stirring a sulfur compound and a cracking catalyst in an aqueous medium to allow liquid-solid separation (step 1); stirring a solid product obtained in the step 1 and a metal component in an aqueous medium to allow liquid-solid separation (step 2); baking a solid product obtained in the step 2 (step 3); and reducing a solid product obtained in the step 3, or reducing a solid product obtained in the step 3, and then subjecting a reduced product to sulfurization treatment (step 4). According to the present invention, the hydrocracking of a raw material oil such as fats and oils and biomass retort oils, or a hydrocarbon or the like in petroleum oils, in a given composition can be accomplished by supplying a low-pressure hydrogen of a normal pressure …
