PROBLEM TO BE SOLVED: To provide a hydrotreating catalyst using a phosphorus-silica-alumina carrier which is improved in desulfurization activity, cracking activity and the like when used for hydrotreating a distillate hydrocarbon oil. Provision of the manufacturing method. A hydrotreating catalyst comprising a phosphorus-silica-alumina carrier carrying at least one metal component selected from Groups VIA and VIII of the Periodic Table, having a specific surface area of 200 m 2 / g As described above, the total pore volume is 0.35 ml / g or more, the average pore diameter is in the range of 60 to 200 °, and the ratio of the pore volume of the average pore diameter ± 30% to the pore volume is 70% or more of the total pore volume. Hydroprocessing catalyst characterized. |
