[Problem] To provide a catalyst for hydrotreating hydrocarbon oil having high desulfurization activity, large abrasion strength and pressure resistance strength, and a method for producing the same. [Solutions] The hydrotreating catalyst uses an alumina-phosphorus carrier, the carrier contains 0.5 to 2.0 mass % of phosphorus on an oxide basis, and each metal of Group 6A and Group 8 of the periodic table is supported on the support, , the specific surface area is 150 m 2 /g or more, the total pore volume measured by the mercury intrusion method is 0.40 to 0.75 ml/g, and in the log differential pore volume distribution measured by the mercury intrusion method, the pore diameter is 6 nm to 13 nm It has two maximal peaks in between, abrasion strength is 0.5 % or less, and pressure-resistant strength is 15 N/mm or more. The carrier is prepared from, for example, a hydrate obtained by adding phosphorus to an alumina hydrate obtained by using a mixture of two types of an aqueous acidic aluminum salt solution and an aqueous basic aluminum salt solution. |
