To provide a hydroprocessing catalyst for hydrocarbon oils, having hydroprocessing (hydrogenation, desulfurization, denitrification and carbon residue removal) performance more excellent the conventional catalysts, and also to provide a method for hydroprocessing a hydrocarbon oil using the catalyst. A process for producing a hydroprocessing catalyst for hydrocarbon oils, loaded with a group 6 element and a group 8 to 10 element of the periodic table and an organic additive, comprising the steps of depositing a boron compound on the pore surfaces of an inorganic porous carrier mainly composed of alumina; calcining to obtain a boron-loaded intermediate product; adding at least one of the group 6 elements of the periodic table by 10 to 40 mass% based on the mass of the oxide catalyst, at least one of the group 8 to 10 elements of the periodic table by 0.5 to 20 mass% based on the mass of the oxide catalyst, and an organic additive by 0.15 to 3 times the moles in total of the group 6 element and the group 8 to 10 element of the periodic table respectively to said intermediate product; and drying. |
