Abstract
The hydrogenation catalyst for heavy hydrocarbon oil includes: at least one of metals in Group 6 of the periodic table being held by a zinc-containing alumina carrier containing 1% by mass to 15% by mass of zinc oxide particles having an average particle diameter of 2 μm to 12 μm based on the carrier; the average pore diameter being 18 nm to 35 nm, and the specific surface area being 70 m/g to 150 m/g. Also, the hydrogenation method for heavy hydrocarbon oil, includes, a catalytic reaction of heavy hydrocarbon oil in the presence of the hydrogenation catalyst, under the conditions of a temperature of 300° C. to 420° C., a pressure of 3 MPa to 20 MPa, a hydrogen/oil ratio of 400 m/mto 3,000 m/m, and a liquid space velocity of 0.1 hto 3 h.
