Abstract

The paper investigates the mass transfer between the liquid and solid phases during the crystallization of granules that contained 60 wt % of powdered ZSM-5 and 40 wt % of amorphous aluminosilicate in a sodium silicate solution. The chemical and phase compositions and the porous properties of the resultant zeolite-containing products were identified. Based on the findings obtained, a stepwise mechanism was suggested for the synthesis of high-crystallinity granular ZSM-5 zeolite with a hierarchical porous structure.

多级多孔结构高结晶粒状ZSM-5合成中液相和固相的传质

摘要

本文研究了在硅酸钠溶液中含有 60 wt% 粉末状 ZSM-5 和 40 wt% 无定形硅铝酸盐的颗粒结晶过程中液相和固相之间的传质。鉴定了所得含沸石产品的化学和相组成以及多孔性质。基于所获得的研究结果，提出了一种逐步合成具有分级多孔结构的高结晶粒状 ZSM-5 沸石的机理。
