MFI ZEOLITE WITH MICROPOROUS AND MESOPOROUS HIERARCHICAL STRUCTURE, PREPARATION METHOD THEREFOR, AND CATALYTIC USE THEREOF

摘要

The present invention relates to: a method for preparing MFI zeolite with a microporous and mesoporous hierarchical structure simultaneously using a first structure-directing agent of a non-benzene base, which provides a framework structure of MFI zeolite seed crystals with a regular microporous pore size, and a second structure-directing agent containing one benzene ring and ammonium ions, which does not interfere with a role of the first structure-directing agent and plays a role as a mesopore-directing agent; MFI zeolite with a microporous and mesoporous hierarchical structure prepared thereby; a catalytic use for a conversion reaction from acetylene thereof into an aromatic compound; and a method for preparing an aromatic compound from acetylene using the catalyst.
