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,
- the hydrotreating catalyst 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,
- wherein a content ratio of said zinc is 0.8 to 10% by mass in terms of an element based on the catalyst, a content ratio of said titanium is 0.03 to 10% by mass in terms of an element based on the catalyst, a content ratio of said at least one metal selected from Group 6 metals in the periodic table is 5 to 16% by mass in terms of an element based on the catalyst, and a content ratio of said at least one metal selected from Group 9 and Group 10 metals in the periodic table is 1 to 5% by mass in terms of an element based on the catalyst.
A method for producing a hydrotreating catalyst for a hydrocarbon oil,
- the method comprising:
- causing a zinc/titanium-containing alumina carrier containing 1 to 14% by mass of zinc in terms of an element based on the carrier and 0.1 to 13% by mass of titanium in terms of an element based on the carrier to support, so as to contain,
- 5 to 16% by mass of at least one metal selected from Group 6 metals in the periodic table in terms of an element based on the catalyst, and 1 to 5% by mass of at least one metal selected from Group 9 and Group 10 metals in the periodic table in terms of an element based on the catalyst.
