Abstract
A composition of matter is provided comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of lamellar symmetry. The composition possesses mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material. Long-range ordering is defined by presence of secondary peaks in an X-ray diffraction (XRD) pattern and/or lamellar symmetry observable by microscopy.

A hydrocracking catalyst comprising hierarchically ordered zeolite material, an inorganic oxide component as a binder, and an active metal component, wherein the hierarchically ordered zeolite material possesses long-range mesoporous ordering of lamellar mesophase symmetry comprising mesopores having walls of zeolite material and a mass of mesostructure between mesopores of zeolite material, whereby the long range mesoporous ordering of lamellar mesophase symmetry is defined by the presence of secondary peaks at 2 theta angle less than 6° in an X-ray diffraction (XRD) pattern and is observable by microscopy including mesopore periodicity repeating over a length of greater than 50 nm.
