Abstract

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

First claim

The invention claimed is:

1. A conversion process comprising contacting a feed with a catalyst at conversion conditions to give at least one product, the catalyst comprising the decomposition product of the decomposition by sulfidation of 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 from 0.001 to 5; ‘b’ varies from 0.1 and 3 ‘M’ is a metal selected from Mg, Mn, Fe, Co, Ni, Cu, Zn, and combinations 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 process of claim 1 wherein the conversion process is hydroprocessing.

3. The process of claim 1 wherein the conversion process is selected from the group consisting of hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

4. The process of claim 1 wherein the transition metal tungsten oxy-hydroxide material, or the decomposition product, or both, are present in a mixture with at least one binder and wherein the mixture comprises up to 25 wt % binder.

5. The process of claim 4 wherein the binder is selected from the group consisting of silicas, aluminas, and silica-aluminas.

6. The process of claim 1 wherein the feed comprises sulfur and the decomposition by sulfidation comprises contacting the metal tungsten oxy-hydroxide material with the sulfur containing feed.

7. The process of claim 1 wherein the decomposition by sulfidation comprises contacting the metal tungsten oxy-hydroxide material with a gaseous mixture of H 2 S/H 2 .

8. The process of claim 1 wherein the sulfidation is conducted at a temperature ranging from about 50° C. to about 600° C.

9. The process of claim 1 wherein the sulfidation is conducted at a temperature ranging from about 150° C. to about 500° C.

10. The process of claim 1 wherein the sulfidation is conducted at a temperature ranging from about 250° C. to about 450° C.

11. A method of making a catalyst comprising the decomposition product of the decomposition by sulfidation of 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 from 0.1 and 3 ‘M’ is a metal selected from Mg, Mn, Fe, Co, Ni, Cu, Zn, and combinations 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;
(d) recovering the transition metal tungsten oxy-hydroxide material; and
(e) decomposing the recovered transition metal tungsten oxy-hydroxide material by sulfidation to generate at least one decomposition product.

12. The method of claim 11 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.

13. The method of claim 11 wherein the recovering is by filtration or centrifugation.

14. The method of claim 11 further comprising adding a binder to the recovered metal tungsten oxy-hydroxide material.

15. The method of claim 14 wherein the binder is selected from the group consisting of aluminas, silicas, and alumina-silicas.
