<P>PROBLEM TO BE SOLVED: To provide a hydroprocessing catalyst without dealing severely with the operation conditions of hydrogenation desulfurizing equipment, demonstrating more excellent desulfurization and denitrification performance, and long in catalyst life. <P>SOLUTION: In the hydroprocessing catalyst for a hydrocarbon oil in which a predetermined amount of at least one selected from among the VIA group metals in the periodic table relative to a catalyst and on an oxide basis, a predetermined amount of at least one selected from among the VIII group metals in the periodic table relative to a catalyst and on an oxide basis, a predetermined amount of carbon derived from an organic acid relative to a catalyst and a predetermined amount or more of a phosphorus oxide relative to a catalyst are supported on an inorganic oxide carrier containing a predetermined amount of titanium atoms relative to a carrier and on an oxide basis and a predetermined amount or less of a phosphorus oxide relative to a carrier, the total amount of the phosphorus oxide contained in the inorganic oxide carrier and the supported phosphorus oxide is a predetermined amount or less relative to the amount of a catalyst, and also a specific surface area, a pore volume and an average pore diameter are within predetermined ranges. <P>COPYRIGHT: (C)2013,JPO&INPIT |
