摘　　要：甲醇制烯烃(MTO)转化是C1化学中最重要的反应之一,它为非石油生产基础石化产品提供了一条途径.自20世纪70年代以来,甲醇转化为烯烃的工艺得到了发展并实现了商业化.许多研究机构和公司在MTO反应的机理研究方面付出了巨大努力,并在MTO工艺研发中采用择形催化剂,如ZSM-5和SAPO-34实现了甲醇高效转化为轻质烯烃、乙烯和丙烯的高选择性.我们对MTO技术的发展进行了简要的综述,并讨论了MTO反应早期初始C―C键形成的反应机制、间接反应机理、沸石和沸石催化剂上甲醇转化的复杂反应以及MTO反应的失活.The conversion of methanol to olefins(MTO)is one of the most important reactions in C1 chemistry,providing a pathway for non petroleum production of basic petrochemical products.Since the 1970s,the process of converting methanol to olefins has been developed and commercialized.Many research institutions and companies have made tremendous efforts in studying the mechanism of MTO reaction,and have used shape selective catalysts such as ZSM-5 and SAPO-34 in the development of MTO process to achieve high selectivity for efficient conversion of methanol to light olefins,ethylene and propylene.This article first provides a brief overview of the development of MTO technology,discussing the reaction mechanism of initial carbon carbon bond formation in the early stage of MTO reaction,indirect reaction mechanism,complex reactions of methanol conversion on zeolite and zeolite catalysts,and deactivation of MTO reaction.
