CATALYST FOR HYDROREFINING VACUUM GAS OIL AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for hydrorefining vacuum gas oil excellent both in desulfurization activity and denitrification activity. ! SOLUTION: There is provided a catalyst for hydrorefining vacuum gas oil consisting of an inorganic composite oxide carrier containing aluminum, silicon, titanium and phosphorus and at least one kind of metal component selected from the Group VIA and the Group VIII in the periodic table, in which the carrier has (a) aluminum content of 70 to 85 mass% in terms of aluminum oxide (Al2O3) based on the total amount of the carrier, (b) the weight ratio of SiO2/Al2O3 of 0.08 to 0.17 and (c) the weight ratio of P2O5/TiO2 in a range of 0.3 to 1.2. !
