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

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.
