Abstract

A hydroprocessing catalyst has been developed. The catalyst is a unique transition metal tungsten oxy-hydroxide material. The hydroprocessing using the transition metal tungsten oxy-hydroxide material may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

First claim

The invention claimed is:

1. A transition metal tungsten oxy-hydroxide material having the formula:
S a (NH 4 ) b M(OH) x W y O z
where ‘S’ is a sugar selected from glucose, fructose, galactose, lactose, maltose, sucrose, and mixtures thereof; ‘a’ varies between 0.001 to 5; ‘b’ varies between 0.1 and 3 ‘M’ is a metal selected from Mg, Mn, Fe, Co Ni, Cu, Zn, and mixtures thereof; ‘x’ varies from 0.1 to 2; ‘y’ varies from 0.1 to 4; z is a number which satisfies the sum of the valences of M, b, x and y; the material having a poorly crystalline diffraction pattern showing a broad peak between d-spacing 4.45-2.25 Å.

2. The transition metal tungsten oxy-hydroxide material of claim 1 wherein the transition metal tungsten oxy-hydroxide material is present in a mixture with at least one binder and wherein the mixture comprises up to 25 wt % binder.

3. The transition metal tungsten oxy-hydroxide material of claim 2 wherein the binder is selected from the group consisting of silicas, aluminas, and silica-aluminas.

4. The transition metal tungsten oxy-hydroxide material of claim 1 wherein M is nickel or cobalt.

5. The transition metal tungsten oxy-hydroxide material of claim 1 wherein M is nickel.

6. The transition metal tungsten oxy-hydroxide material of claim 1 wherein the transition metal tungsten oxy-hydroxide material is sulfided.

7. A method of making a transition metal tungsten oxy-hydroxide material having the formula:
S a (NH 4 ) b M(OH) x W y O z
where ‘S’ is a sugar selected from glucose, fructose, galactose, lactose, maltose, sucrose, and mixtures thereof; ‘a’ varies between 0.001 to 5; ‘b’ varies between 0.1 and 3 ‘M’ is a metal selected from Mg, Mn, Fe, Co Ni, Cu, Zn, and mixtures thereof; ‘x’ varies from 0.1 to 2; ‘y’ varies from 0.1 to 4; z is a number which satisfies the sum of the valences of M, b, x and y; the material having a poorly crystalline diffraction pattern showing a broad peak between d-spacing 4.45-2.25 Å, the method comprising:
(a) forming a reaction mixture containing NH 3 , H 2 O, and sources of S, M, and W;
(b) adjusting the pH of the reaction mixture to a pH of from about 8.5 to about 10;
(c) reacting the reaction mixture; and
(d) recovering the transition metal tungsten oxy-hydroxide material.

8. The method of claim 7 wherein the reacting is conducted at a temperature ranging from about 60° C. to about 120° C. for a period of time ranging from 30 minutes to around 2 days.

9. The method of claim 7 wherein the recovering is by filtration or centrifugation.

10. The method of claim 7 further comprising adding a binder to the recovered metal tungsten oxy-hydroxide material.

11. The method of claim 10 wherein the binder is selected from the group consisting of aluminas, silicas, and alumina-silicas.

12. The method of claim 7 further comprising sulfiding the recovered transition metal tungsten oxy-hydroxide material.

13. A conversion process comprising contacting a feed with a catalyst at conversion conditions to give at least one product, the catalyst comprising a metal tungsten oxy-hydroxide material having the formula:
S a (NH 4 ) b M(OH) x W y O z
where ‘S’ is a sugar selected from glucose, fructose, galactose, lactose, maltose, sucrose, and mixtures thereof; ‘a’ varies between 0.001 to 5; ‘b’ varies between 0.1 and 3 ‘M’ is a metal selected from Mg, Mn, Fe, Co Ni, Cu, Zn, and mixtures thereof; ‘x’ varies from 0.1 to 2; ‘y’ varies from 0.1 to 4; z is a number which satisfies the sum of the valences of M, b, x and y; the material having a poorly crystalline diffraction pattern showing a broad peak between d-spacing 4.45-2.25 Å.

14. The process of claim 13 wherein the conversion process is hydroprocessing.

15. The process of claim 13 wherein the conversion process is selected from the group consisting of hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

16. The process of claim 13 wherein the transition metal tungsten oxy-hydroxide material is present in a mixture with at least one binder and wherein the mixture comprises up to 25 wt % binder.

17. The process of claim 13 wherein the transition metal tungsten oxy-hydroxide material is sulfided.
