| 摘 要： | 具有CHA结构的SAPO-34分子筛因其优异的理化性质被认为是甲醇制烯烃(MTO)工艺的最佳催化剂,但CHA结构中狭窄的八元环孔会限制扩散,使催化剂易于失活降低使用寿命.本文从构建多级孔结构和减小分子筛粒径入手,综述了具有优异的MTO催化性能的多级孔和纳米级SAPO-34分子筛的最新进展,分析不同制备方法对SAPO-3...

| Abstract: | SAPO-34 zeolite with CHA structure is considered as the best catalyst for methanol-to-olefin(MTO) process due to its excellent physicochemical properties.However,the narrow eight-ring pores in the CHA structure limit diffusion and make the catalyst suffering from rapid deactivation and lifetime reduction.This article reviews the latest preparation methods of hierarchical and nanosized SAPO-34 catalysts with excellent MTO performance,analyzes the effects of preparation methods on the crystal size,surface area,pores and acid sites of SAPO-34 catalysts,and their effects on MTO reactions.The essay also puts forward the existing problems and future development direction. |
