Hydrogenation catalyst for heavy hydrocarbon oil, production method for hydrogenation catalyst for heavy hydrocarbon oil, and hydrogenation method for heavy hydrocarbon oil

A production method for a hydrogenation catalyst for heavy hydrocarbon oil, comprising:

• a step of preparing an alumina gel;
• a step of kneading the alumina gel with a phosphorous compound and a zinc compound such that 0.1% by mass to 4% by mass, in terms of oxide based on a carrier, of phosphorous, and 1% by mass to 12% by mass, based on a carrier, of zinc oxide particles having an average particle diameter of 2 μm to 12 μm are incorporated;
• a step of obtaining a phosphorous-zinc-containing alumina carrier by molding the obtained kneaded mixture, and drying and calcining a molded product;
• and
• a step of supporting, on the phosphorous-zinc-containing alumina carrier, at least one selected from metals in Group 6 of the periodic table and at least one selected from metals in Groups 8 to 10 of the periodic table such that 8% by mass to 20% by mass, in terms of oxide based on a catalyst, of at least one selected from metals in Group 6 of the periodic table and 2% by mass to 6% by mass, in terms of oxide based on a catalyst, of at least one selected from metals in Groups 8 to 10 of the periodic table are incorporated.
