This catalyst is a hydrogenation desulfurization catalyst that supports one or more metals selected from a group formed from the group 6 elements of the long period periodic table, one or more metals selected from a group formed from the group 9 elements and the group 10 elements of the same, phosphorus, and an organic acid on a composite oxide carrier having a specific content of both alumina and HY zeolite having a specific crystallite size and the like. The catalyst basis in an oxide conversion includes 10 - 40% by mass of the group 6 metal, 1 - 15% by mass of the group 9 and group 10 metals, and 1.5 - 8% by mass phosphorus. The catalyst basis in an element conversion includes 0.8 - 7 percent by mass of carbon derived from an organic acid and for each mole of the group 9 element and group 10 element metals, the same includes 0.2 - 1.2 moles of the organic acid. The average poor diameter at a specific surface area, pore volume, and pore distribution is within a specific range. |
