CATALYST FOR HYDROGENATING HEAVY HYDROCARBON OIL, ITS PRODUCTION METHOD, AND METHOD FOR HYDROGENATING HEAVY HYDROCARBON OIL USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for hydrogenating heavy hydrocarbon oil which uses a small amount of noble metals, is high in hydrogenation activity, and has high sulfur resistance and a long life and a method for producing the catalyst. SOLUTION: The catalyst for hydrogenating the heavy hydrocarbon oil contains (A) at least one compound of an element selected from group 6 elements and group 8-10 base metal elements of the periodic table and (B) at least one compound of an element selected from group 8-10 noble metal elements. A reduction peek temperature by a temperature elevation reduction method belonging to the compound (A) is 500 deg.C or lower. A method for hydrogenating the heavy hydrocarbon oil uses the catalyst. In the method for producing the catalyst, the compound (A) is supported on a carrier, subjected to reduction treatment, and brought into contact with a solution of the compound (B).
