A method for producing a hydrocarbon liquid fuel, the method is as follows: in the presence of a catalytic hydrocracking catalyst, the supply pressure of hydrogen is set to 0.1 to 1.0 MPa, and the liquid space velocity of the liquid amount of the raw oil is set to 0.05 to 10.0 h -1 , and the hydrogen flow rate per 1 L of the feedstock oil is set to 50 to 3,000NL, and the feedstock oil is subjected to catalytic hydrocracking to produce a hydrocarbon liquid fuel, and in the method for producing a hydrocarbon liquid fuel, the catalytic hydrocracking catalyst is prepared by comprising: Prepared by the method of the following steps: step 1, stirring the sulfur compound and the cracking catalyst in an aqueous medium to perform solid-liquid separation; step 2, stirring the solid matter and metal component obtained in step 1 in an aqueous medium to perform solid-liquid separation ; Step 3, calcining the solid obtained in Step 2; and Step 4, reducing the solid obtained in Step 3, or reducing the solid obtained in Step 3 and then subjecting it to a sulfidation treatment. According to the present invention, the catalytic hydrocracking of oil and fats, biomass retort oil, or raw oil such as hydrocarbons in petroleum can be realized under the supply of low-pressure hydrogen at about normal pressure according to a predetermined formulation. |
