| 英文摘要 | hierarchical mcm-49 zeolite with intracrystalline mesopores was prepared through post-treating the conventional mcm-49 zeolite in hexadecyltrimethylammonium bromide (ctab) and naoh mixed solution. n-2 adsorption and desorption, xrd, tem, xrf, icp and py-ir techniques were applied to characterize the obtained samples. it was found that uniform intracrystalline mesopores were distributed in the mcm-49 crystals, and the intracrystalline meso-porosity could be modified by changing the post-treatment conditions such as ctab concentration, naoh concentration, temperature and time. based on the characterization results upon the hierarchical mcm-49 zeolite samples obtained by post-treating different time, the formation of intracrystalline mesopores in mcm-49 zeolite was proposed, which followed a ctab micelle directed desilication mechanism. by virtue of the intracrystalline mesopores, the hierarchical mcm-49 zeolite prepared under proper post-treatment condition exhibited superior stability than the conventional mcm-49 zeolite in liquid alkylation of benzene with ethylene.
