MODIFIED ZEOLITES Y WITH TRIMODAL INTRACRYSTALLINE STRUCTURE, METHOD FOR PRODUCTION THEREOF AND USE THEREOF

摘要

FIELD: chemistry.SUBSTANCE: invention relates to catalysis. The invention relates to a zeolite Y with a modified faujasite structure, the intracrystalline structure of which contains at least one micropore system, at least one system of fine mesopores with average diametre of 2-5 nm and at least one system of large mesopores with average diametre of 10-50 nm. The invention also relates to particles which contain such zeolites, as well as use thereof in oil refinement, particularly as a hydrocracking catalyst.EFFECT: high activity.17 cl, 10 dwg, 1 tbl, 4 ex
