AI Technical Summary
Technical Problem
Conventional methods for generating hierarchically ordered zeolites lack control over long-range mesoporous ordering and often result in poorly interconnected mesopores, limiting their effectiveness in applications requiring larger molecular species diffusion and stability.
Method used
A composition of hierarchically ordered zeolites with defined long-range mesoporous order is achieved by base-mediated reassembly, using supramolecular templates and ionic cosolutes to control the decomposition and reassembly of parent zeolite crystals into oligomeric units, forming a cubic-symmetric mesoporous structure.
Benefits of technology
The method produces zeolites with improved mass transfer, reduced coking, and enhanced catalyst performance, suitable for hydrocracking processes.

Abstract
A composition is provided that includes a hierarchical ordered crystalline microporous material having a cubic-symmetric defined long-range mesoporous order. The composition possesses mesopores having the walls of the crystalline microporous material and a group of mesostructures between the mesopores of the crystalline microporous material. The long-range order is defined by the presence of secondary peaks in the X-ray diffraction (XRD) pattern and / or cubic symmetry observable by microscopy.
