Title: Catalytic hydrocracking, hydrodesulfurization, and/or hydrodenitrogenation of organic compounds employing promoted zinc titanate and a zeolite as the catalytic agent
Abstract:The catalytic hydrocracking, hydrodesulfurization, and/or hydrodenitrogenation of organic compounds is carried out in the presence of a catalyst composition comprising zeolite, zinc, titanium, and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium and compounds thereof.
Inventor(s): Gardner; Lloyd E. (Bartlesville, OK)
Assignee: Phillips Petroleum Company (Bartlesville, OK)
Filing Date:Jan 18, 1982
Application Number:06/340,148
Claims:1. A catalyst composition comprising zeolite, zinc, titanium, and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium, and compounds thereof.

2. A composition in accordance with claim 1 wherein said zinc and titanium are present in said catalyst composition in the form of zinc titanate prepared by calcining a mixture of zinc oxide and titanium dioxide in the presence of molecular oxygen at a temperature in the range of about 650.degree. C. to about 1050.degree. C.

3. A composition in accordance with claim 2 wherein the atomic rato of zinc to titanium in said catalyst composition is in the range of about 1:1 to about 3:1.

4. A composition in accordance with claim 2 wherein the atomic ratio of zinc to titanium in said catalyst composition is in the range of about 1.8:1 to about 2.2:1.

5. A composition in accordance with claim 1 wherein the concentration of said zeolite is in the range of about 1 to about 60 weight percent based on the weight of said catalyst composition.

6. A composition in accordance with claim 1 wherein the concentration of said zeolite is in the range of about 10 to about 40 weight percent based on the weight of said catalyst composition.

7. A composition in accordance with claim 1 wherein said zeolite is a Y-type zeolite having a sodium content not greater than about 0.5 weight percent.

8. A composition in accordance with claim 1 wherein said zeolite is a Y-type zeolite having a sodium content not greater than about 0.2 weight percent.

9. A composition in accordance with claim 1 wherein the concentration of vanadium, chromium, cobalt, nickel, molybdenum, or tungsten as individual promoters, expressed as an element, if present, is in the range of about 0.1 to about 16 weight percent based on the weight of said catalyst composition and the concentration of rhenium, palladium, rhodium, ruthenium or platinum as individual promoters, expressed as the element, if present, is in the range of about 0.2 to about 1.6 weight percent based on the weight of said catalyst composition.

10. A composition in accordance with claim 9 wherein the total concentration of any combination of the group from which said at least one promoter is selected, expressed as an element, is in the range of about 0.1 to about 24 weight percent based on the weight of said catalyst composition.

11. A composition in accordance with claim 10 wherein said catalyst composition has been calcined in the presence of molecular oxygen at a temperature in the range of about 500.degree. C. to about 650.degree. C.

12. A composition in accordance with claim 1 wherein said at least one promoter is cobalt and molybdenum.

13. A composition in accordance with claim 12 wherein the cobalt:molybdenum atomic ratio in said catalyst composition is in the range of about 0.6:1 to about 0.8:1.

14. A composition in accordance with claim 1 wherein said catalyst composition is completely sulfided.
