摘要
多级孔ZSM-5分子筛结合了微孔分子筛可调变的酸性、良好的水热稳定性以及介孔材料优异的传质扩散性能,在催化领域有着广阔的应用前景.我们综述了近年来多级孔ZSM-5分子筛的研究进展,重点概述了多级孔ZSM-5分子筛的不同制备方法,包括后处理法、硬模板法和软模板法等,同时介绍了多级孔ZSM-5分子筛在炼油领域的应用研究,并在上述基础上对多级孔ZSM-5分子筛的研究趋势进行了展望.
The hierarchical ZSM-5 zeolite integrates the merits of both microporous zeolite and mesoporous materi- al. It possesses not only adjustable acidity and high hydrothermal stability, but also excellent diffusivity. Conse- quently, the hierarchical ZSM-5 zeolite has a wide application prospect in catalytic fields. The research progress of hierarchical ZSM-5 zeolite was reviewed, with the main focus on the synthesis strategies including post-treatment method, hard-templating method and soft-templating method. Meanwhile the applications of hierarchical ZSM-5 zeolite in oil refining field were introduced. Finally, the development trends of hierarchical ZSM-5 are prospected.
