A unique crystalline bis-ammonia transition metal molybdate tungstate material has been developed. This material can be used as a hydrotreating catalyst. The hydrotreatment can include hydrogen denitrification, hydrodesulfurization, hydrodemetallation, hydrogenated dearomatics, hydrotreated silicic acid, hydrogenation isomerization, hydrotreatment, hydrogenation purification, and hydrocracking. |
