预先负载原料法合成ZSM-5/SAPO-5复合分子筛
ZSM-5/SAPO-5 Composite Molecular SievesSynthesized by Preloading Raw Material Method
摘要
Abstract
ZSM-5 (core)/SAPO-5 ( shell) binary structure composite molecular sieves were synthesized by preloading raw material method. The effect of loading conditions on the formation and character of core/shell structure zeolite was investigated. These synthesized samples were characterized by XRD, SEM, EDS and FTIR, respectively. The results indicate that the pretreated condition affects the combination of phosphorus and ZSM-5, the crystallinity and particle morphology of composite significantly. Compared to hydrothermal synthesis method, this approach is helpful to forming smaller SAPO-5 particles and growing SAPO-5 on ZSM-5 surface under suitable pretreated condition.关键词
