Abstract

A hydroprocessing catalyst has been developed. The catalyst is a unique transition metal tungstate material. The hydroprocessing using the crystalline ammonia transition metal dimolybdotungstate material may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

First claim

The invention claimed is:

1. A crystalline transition metal tungstate material having the formula:
(NH 4 ) x MW y O z

where ‘x’ varies from 0.1 to 3; ‘M’ is a metal selected from Mg, Mn, Fe, Co Ni, Cu, Zn, and mixtures thereof; ‘y’ ranges from 1 to 10; and z is a number which satisfies the sum of the valences of x, M and y; the material having a unique x-ray powder diffraction pattern showing peaks at the d-spacings listed in Table A:

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

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

4. The crystalline transition metal tungstate material of claim 1 wherein M is nickel or cobalt.

5. The crystalline transition metal tungstate material of claim 1 wherein M is nickel.

6. The crystalline transition metal tungstate material of claim 1 wherein the crystalline transition metal tungstate material is sulfided.
