Abstract
A hydrotreating catalyst for a hydrocarbon oil is provided in which at least one metal selected from Group 6 metals in the periodic table and at least one metal selected from Group 9 and Group 10 metals in the periodic table are supported on a zinc/titanium-containing alumina carrier containing zinc and titanium.
Claims9
A hydrotreating catalyst for a hydrocarbon oil,
- wherein the hydrotreating catalyst comprises at least one metal selected from Group 6 metals in the periodic table and at least one metal selected from Group 9 and Group 10 metals in the periodic table supported on a zinc/titanium-containing alumina carrier,
- wherein a content of said zinc is 0.8 to 10% by mass based on a total mass of the catalyst, a content of said titanium is 0.03 to 10% by mass based on the total mass of the catalyst, a content of said at least one metal selected from Group 6 metals in the periodic table is 5 to 16% by mass based on the total mass of the catalyst, a content of said at least one metal selected from Group 9 and Group 10 metals in the periodic table is 1 to 5% by mass based on the total mass of the catalyst, and wherein a molar ratio of titanium with respect to zinc in the hydrotreating catalyst is 2 to 12.
