Abstract
The invention relates to a Y-type zeolite having a modified faujasite structure, the intracrystalline structure of which includes at least one network of micropores, at least one network of small mesopores having an average diameter ranging from 2 to 5 nm, and at least one network of large mesopores having an average diameter ranging from 10 to 50 nm. The invention also relates to particles including such zeolites and to the use thereof in a method for processing crude oil, particularly as a hydrocracking catalyst.
