CATALYST FOR HYDROGENATION TREATMENT OF HYDROCARBON OIL AND METHOD FOR PREPARATION THEREOF, AND METHOD FOR HYDROGENATION TREATMENT OF HYDROCARBON OIL

摘要

A catalyst for the hydrogenation treatment of a hydrocarbon oil, which comprises an inorganic oxide carrier containing a specific amount of a phosphorus oxide and, carried thereon, specific amounts of at least one of metals belonging to 6 Group of the Periodic Table, at least one of metals belonging to 8 Group of the Periodic Table and carbon, and has specific values of a specific surface area, a pore volume and an average pore diameter; a method for preparing the catalyst; and a method for the hydrogenation treatment of an hydrocarbon oil using the catalyst. The catalyst allows the desulfurization of a hydrocarbon oil in a high degree, without the need for a severe operation condition, and simultaneously allows the reduction of the content of a nitrogen compound, and also can be prepared with a simple and easy means.
