Abstract

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