Abstract

A unique crystalline bis-ammonia transition metal molybdotungstate material has been developed. The material may be used as a hydroprocessing catalyst. The hydroprocessing may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodearomatization, hydrodesilication, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.
