摘要
Provided are a beta molecular sieve having multi-level channels and synthesizing method thereof. The molecular sieve has a second-level mesoporous structure and comprises polyquaternium-6, polyquaternium-7, polyquaternium-22 or quaternium-39 as a guiding agent for both micropores and mesopores during the synthesizing process. The present invention uses cheap raw materials and a simple synthesizing method and has broad industrial application prospects.
