Abstract

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

First claim

1 . A conversion process comprising contacting a feed with a catalyst at conversion conditions to provide at least one product, the catalyst comprising a component produced upon decomposition by sulfidation of a transition metal molybdotungsten oxy-hydroxide material having the formula:
S a (NH 4 ) b M(OH) c Mo x W y O z
where ‘S’ is 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; ‘c’ varies from 0.1 to 2; ‘x’ varies from 0.01 to 1; ‘y’ varies from 0.1 to 4; the sum of (x+y) must be ≤4.0; z is a number which satisfies the sum of the valences of M, b, c, x and y; the material having a poorly crystalline x-ray powder diffraction pattern showing a broad peak between d-spacing 4.45 and 2.25 Å.

2 . The process of claim 1 wherein the conversion process is hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, or hydrocracking.

3 . The process of claim 1 wherein the conversion process is hydroprocessing.

4 . The process of claim 1 wherein the catalyst is present in a mixture with at least one binder and wherein the mixture comprises up to 25 wt % binder.

5 . The process of claim 1 wherein the binder is selected from the group consisting of silicas, aluminas, and silica-aluminas.

6 . The process of claim 1 wherein M of the transition metal molybdotungsten oxy-hydroxide material is nickel or cobalt.

7 . The process of claim 1 wherein M of the transition metal molybdotungsten oxy-hydroxide material is nickel.

8 . The process of claim 1 wherein the feed comprises sulfur and the sulfidation comprises contacting the transition metal molybdotungsten oxy-hydroxide material with the sulfur containing feed.

9 . The process of claim 1 wherein the sulfidation comprises contacting the transition metal molybdotungsten oxy-hydroxide material with a gaseous mixture of H 2 S/H 2 .

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

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

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