Abstract

Abstract

ZSM-5 molecular sieve was synthesized by water heat from a weathered rock in Huizhou, Guangdong Province。Firstly, the kaolin from the weathered rock was recovered by beneficiation. Reduction-complexation method was used to chemically remove iron from it. Next the kaolin was thermally activated and ZSM-5 molecular sieve was synthesized by hydrothermal method using TPAOH as a template. The samples were characterized by TEM, XRD and N₂ adsorption-desorption. The results showed that the ZSM-5 molecular sieve had a certain mesoporous structure, good crystallinity and regular pores.
