BETA MOLECULAR SIEVE HAVING MULTI-LEVEL CHANNEL STRUCTURE, AND PREPARATION METHOD THEREOF

摘要

Provided is a Beta molecular sieve having multi-level channels and synthesis method thereof The molecular sieve has a two-level mesoporous structure and uses polyquaternium-6, polyquaternium-7, polyquaternium-22, or polyquaternium-39 as a guiding agent for both micropores and mesopores during the process of synthesis. The present invention uses cheap raw materials and a simple synthesis method, and has broad industrial application prospect.
