In order to provide a hydroprocessing catalyst capable of improving the storage stability of a hydroprocessed heavy hydrocarbon oil without reducing the desulfurization activity and demetalization activity, a method for manufacturing the hydroprocessing catalyst, and a method for hydroprocessing a heavy hydrocarbon oil using the hydroprocessing catalyst, the present invention provides a hydroprocessing catalyst for a heavy hydrocarbon oil characterized in having, as a carrier, a phosphorus/silica-containing alumina containing 0.1-4 mass% of phosphorus based on the carrier and in terms of an oxide and 0.1-1.5 mass% of silica based on the carrier, the carrier carrying 8-20 mass% of at least one metal selected from group 6 metals on the periodic table based on the catalyst and in terms of an oxide and 2-6 mass% of at least one metal selected from group 8-10 metals on the periodic table based on the catalyst and in terms of an oxide. |
