AI Technical Summary

Technical Problem

Existing methods for generating hierarchically ordered zeolites lack control over the long-range ordering and size of mesopores, leading to inefficient diffusion and susceptibility to coking, which hampers their performance in catalytic reactions.

Method used

A composition of hierarchically ordered crystalline microporous materials with defined long-range mesoporous order is achieved by base-mediated reassembly of parent CMMs, using supramolecular templates and ionic cosolutes to induce hexagonal symmetry, minimizing diffusion into micropores and promoting controlled reassembly into a hierarchical structure.

Benefits of technology

The resulting materials exhibit improved mass transfer, reduced coking, and enhanced catalyst performance, with defined long-range mesoporous order and hexagonal symmetry, suitable for applications like hydrocracking hydrocarbon oils.

Abstract

A composition is provided that includes a hierarchical ordered crystalline microporous material having a hexagonal symmetric defined long-range mesoporous order. The composition possesses mesopores having 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 an X-ray diffraction (XRD) pattern and / or by hexagonal symmetry observable by microscopy.
