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.
Claims6
A crystalline transition metal tungstate material having the formula:
- MWxOy
- 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:
