Zeolites hydrotreating/hydrocracking

A fairly large number of patents has been issued describing the application of aluminum-deficient Y zeolites in different areas of catalysis. Ultrastable Y zeolites have been used in the preparation of catalysts applied in hydrocarbon cracking, e.g. (94,95) hydrocracking, e.g. (96,97) hydrotreating, e.g. (98) and disproportionation, e.g. (99).

One patent application (30) describes the use of zeolite/TUD-1/ metal function for various refining processes, including hydrotreating, middle distillate hydrocracking, hydrocracking for lubes (commonly called lubes hydrocracking ), and hydroisomerization of heavy distillate.
