Abstract

A hydroprocessing catalyst has been developed. The catalyst is a crystalline transition metal tungstate material or metal sulfides derived therefrom, or both. The hydroprocessing using the crystalline transition metal tungstate 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:
MW x O y

where ‘M’ is a metal selected from Mn, Fe, Co, Ni, V, Cu, Zn, Sn, Sb, Ti, Zr and mixtures thereof; ‘x’ varies from 0.35 to 2, ‘y’ is a number which satisfies the sum of the valency of M and W; the material is further characterized by a unique x-ray powder diffraction pattern showing peaks at the d-spacings listed in Table A:

wherein, relative intensities of the d-spacings are indicated by the notations vs, s, and m, which represent very strong, strong, and medium, respectively.

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, silica-aluminas, and mixtures thereof.

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.
