Abstract
A highly active hydroprocessing catalyst that comprises a doped support having been impregnated with a metal-impregnation solution, comprising a complexing agent and a hydrogenation metal, and filled with an organic additive blend. The catalyst is made by providing a doped support particle followed by impregnating the doped support particle with a metal impregnation solution that contains both a hydrogenation metal component and a complexing agent component to provide a metal-impregnated doped support particle. The metal-impregnated doped support particle is dried, but not calcined, and impregnated with an organic additive blend component.
Claims17
A method of making a hydroprocessing catalyst, the method comprises:
- providing a doped support particle, comprising a dopant and an inorganic oxide;
- impregnating said doped support particle with a metal impregnation solution, comprising at least one hydrogenation metal component and a metal complexing agent, to provide a metal-impregnated doped support particle;
- drying said metal-impregnated doped support particle to provide a dried particle;
- impregnating the dried particle with an organic additive blend, comprising an acetate compound and an unsaturated fatty amine compound to provide said hydroprocessing catalyst;
- and wherein said dopant is either nickel or boron and said doped support particle comprises from 0.01 wt. % to 5 wt. % of said dopant.
A hydroprocessing catalyst, comprising:
- a doped support particle, comprising an inorganic oxide and from 0.01 to 5 wt. % nickel or boron, or both;
- an overlayer mixture of a metal complexing agent, molybdenum, and either cobalt or nickel, or both;
- and
- an impregnated organic additive blend, comprising an acetate compound and an unsaturated fatty amine.
A hydroprocessing catalyst, comprising:
- a doped support particle, comprising an inorganic oxide and from 0.01 to 5 wt. % nickel or boron, or both, impregnated with a metal impregnation solution, including a metal complexing agent, molybdenum, and either nickel or cobalt, or both;
- and
- further having incorporated therein an organic additive blend, comprising an acetate compound and unsaturated fatty amine compound;
- wherein said either nickel or cobalt, or both, is present in said hydroprocessing catalyst in an amount in the range of from 0.5 to 20 wt. %, and said molybdenum is present in said hydroprocessing catalyst in an amount in the range of from 5 to 50 wt. %, with the wt. % based the metal as the element regardless of its actual form and the dry doped support particle, excluding said organic additive blend;
- and wherein said organic additive blend has a weight ratio of unsaturated fatty amine compound-to-acetate compound in the range from 30/70 to 90/10.
