HYDROGEN TREATING CATALYST FOR HYDROCARBON OIL AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To produce a hydrogen treating catalyst so excellent in desulfurization activity as to make the sulfur content of a hydrocarbon oil as low as possible. SOLUTION: At least one selected from the group VIA metallic elements of the Periodic Table at least one selected from the group VIII metallic elements of the Periodic Table, phosphorus and boron are carried on a carrier comprising alumina or an alumina-base inorg. oxide by 10-30 mass%, 1-10 mass%, 1-7 mass% and 0.5-7 mass% (expressed in terms of oxides), respectively, based on the total amt. of the resultant catalyst to obtain the objective hydrogen treating catalyst. The carrier may contain 1-15 mass% zeolite based on the total amt. of the catalyst. The catalyst is produced by impregnating a fluid contg. the components into the carrier.
