| 英文摘要 | the effects of alkali-treatment on the compositions, acidities, texture properties and pore structures of template-containing mcm-22 zeolite were studied by py-ir, n-2 adsorption-desorption, o-xylene adsorption, xrd and si-29 nmr. when template-containing mcm-22 zeolite was alkali-treated, desilication mainly occurred in the al-poor regions, which broke the crystal sheets into smaller ones. the alkali-treatment process under the moderate conditions had little influence on the microporous properties and crystal structures of mcm-22 zeolite, but improved the diffusion conditions for aromatics mainly by reducing the crystal size. with the preserved framework al species, the alkali-treated template-containing mcm-22 samples had higher ratio of bronsted to lewis acid sites, and exhibited improved catalytic performances in alkylation and transalkylation processes.
