Abstract

Abstract: Core-shell ZSM-5/silicalite-1 samples were synthesized by epitaxial growth of silicalite-1 shell on ZSM-5 core crystallites. This core-shell zeolite has good shape-selective catalytic performance for alkylation of toluene with methanol, in which p-xylene is selectively formed.

Key words: core-shell zeolite, ZSM-5 zeolite, silicalite-1, toluene, methylation, xylene, shape selectivity
