摘　　要：综述了生物质甲醇/二甲醚制烯烃(methanol to olefins/dimethyl ether to olefins,MTO/DTO)中发挥催化作用的分子筛的种类及性能特点,对ZSM-5分子筛和SAPO-34分子筛的合成方法和改性方法进行了阐述,重点分析了水热合成法、无模板剂合成法、微波合成法、干凝胶合成法、无溶剂合成法、离子热合成法和超声波合成法等合成方法,以及改变硅铝比、金属改性、非金属改性、碱改性、水热处理改性、酸改性、氨基化改性和氟化物处理改性等改性方法。目前,分子筛的合成方法和改性方法对分子筛性能的调控仍有不足,而分子筛的性能与其结构及酸性密切相关。调控分子筛的结构及酸性,可以进一步提升分子筛的催化性能与合成效率,延长分子筛的催化寿命,降低甲醇/二甲醚生产的工艺成本,减少对环境的危害。This article summarizes the types and performance characteristics of molecular sieves that play a catalytic role in the production of olefins from biomass methanol/dimethyl ether(MTO/DTO),and the synthesis and modification methods of ZSM-5 molecular sieves and SAPO-34 molecular sieves are described.The synthesis methods such as hydrothermal synthesis,template free synthesis,microwave synthesis,dry gel synthesis,solvent-free synthesis,ionothermal method,ultrasonic method,etc.,as well as the modification methods such as changing the silicon aluminum ratio,metal modification,non-metallic modification,alkali modification,hydrothermal treatment modification,acid modification,amination modification,fluoride treatment modification,etc.were emphatically analyzed.At present,the synthesis and modification methods of molecular sieves still have insufficient control over their performances.While,the performance of molecular sieves is closely related to their structure and acidity.Regulating the structure and acidity of molecular sieves can further improve their catalytic performance and synthesis efficiency,prolong their catalytic life,reduce the process cost of methanol/dimethyl ether production,and minimize environmental hazards.
