Hydrogenation method of processing heavy hydrocarbon oil using the catalyst and hydrotreating catalyst

摘要

PROBLEM TO BE SOLVED: To provide a hydrogenation catalyst having high desulfurizing activity at lower temperatures and resistance against accumulation of metals and to provide a method for hydrogenation of heavy hydrocarbon oil by using the hydrogenation catalyst.;SOLUTION: This catalyst is prepared by depositing at least one metal selected from the group VI metals and at least one metal selected from the group VIII to X metals in the periodic table on an alumina carrier containing 1 to 10 mass % silica. The catalyst has 100 to 170 Å average pore diameter(PD) and 140 to 250 m2/g specific surface area(SA) satisfying formula (1): SA+1.65PD410, and 0.4 to 1.0 cc/g whole pore volume. The catalyst is used for the hydrogenation of heavy hydrocarbon oil.;COPYRIGHT: (C)2001,JPO
