Inferior hydrocarbon oil material hydrotreating method

An inferior hydrocarbon oil material hydrotreating method is as follows: under the condition of hydrotreating reactions, raw oil sequentially contacts with a catalyst composition comprising a hydrotreatment protection catalyst I, a hydrotreatment catalyst II and a hydrotreatment catalyst III, wherein the hydrotreatment protection catalyst I contains an alumina carrier, the alumina carrier has a bimodal pore structure, contains at least one aid selected from boron, silicon and fluorine aids, and is characterized by mercury intrusion method, the pore volume of the alumina carrier is 0.3-0.8mL/g, the specific surface area is 70-220m /g, the pore volume of pores with the diameter of 6-10nm is 8-25% of the total pore volume, and the pore volume of pores with the diameter of 85-160nm is 40-75% of the total pore volume. The method disclosed in the invention has a better inferior raw oil hydrotreatment performance than existing methods.
