Process for mild hydrocracking of petroleum cuts using a catalyst containing at least two dealuminated Y zeolites

摘要

A mild hydroconversion process for petroleum cuts using a catalyst comprising at least one matrix, at least one Y zeolite with a lattice parameter which is in the range 24.15 ANGSTROM to 24.38 ANGSTROM (1 nm-10 ANGSTROM ), at least one Y zeolite with a lattice parameter of more than 24.38 ANGSTROM and less than or equal to 24.51 ANGSTROM , and at least one hydro-dehydrogenating element.
