Abstract

A hydroprocessing catalyst or catalyst precursor has been developed. The catalyst is a transition metal tungstate material, or the decomposition product thereof. The hydroprocessing using the crystalline transition metal molybdotungstate material may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.
