PROCESS FOR PREPARING AN INDUSTRIAL HYDROCONVERSION CATALYST, CATALYST THUS OBTAINED AND USE THEREOF IN A HYDROCONVERSION PROCESS

摘要

The invention relates to a process for preparing a hydreconversion catalyst based on modified zeolite Y, comprising the steps of: A- preparation of a modified zeolite Y, whose intracrystalline structure presents at least one network of micropores, at least one network of small mesopores with a mean diameter of 2 to 5 nm and at least one network of large mesopores with a mean diameter of 10 to 50 nm, these various networks being interconnected; B- mixing the zeolite with a binder, shaping the mixture and then calcining; C- introducing at least one catalytic metal chosen from metals of group VIII and/or of group VIB, followed by calcination. The invention also relates to a catalyst obtained via this process and also to the use thereof.
