CATALYST BASED ON A SILICON-CONTAINING MATERIAL WITH HIERARCHICAL POROSITY AND METHOD FOR THE HYDROCRACKING/HYDROCONVERSION AND HYDROPROCESSING OF HYDROCARBON FEEDSTOCKS

摘要

Catalyst comprises a support formed of a material with hierarchical porosity comprising silicon and at least two elementary spherical particles, where each of the spherical particles comprises zeolitic nanocrystals having a pore size of 0.2-2 nm and a silicon oxide matrix, mesostructured with a pore size of 1.5-30 nm and having amorphous wall with thickness of 1-30 nm, where the elementary spherical particles has a maximum diameter of 100 mu m; and an active phase containing a hydro-dehydrogenating element of group VIB and/or group VIII of the periodic table. Independent claims are included for: (1) a hydrocarbon hydrocracking and/or hydroconversion process using the catalyst; and (2) a hydrotreatment process of hydrocarbon charges using the catalyst.
