中文摘要：

乙烯和丙烯是重要的化工原料,目前烯烃生产技术严重依赖石油,在石油资源日益紧缺的今天,烯烃的需求量却一直快速增长,尤其是丙烯。因此,以煤或天然气为原料制备甲醇进而生产乙烯和丙烯的替代路线,逐渐受到学术界和工业界的重视。近年来,甲醇制烯烃技术在基础研究和工业放大方面都获得了快速的发展。本文综述了甲醇制烯烃常用催化剂ZSM-5和SAPO分子筛的改性及催化性能研究;对甲醇制烯烃的反应机理进行了总结,讨论了碳池机理的最新研究成果;并对甲醇制烯烃和甲醇制丙烯的工艺开发和工业放大进展进行了介绍。

英文摘要：

Ethylene and propylene are important chemical materials and manufactured from petroleum at present.However,the oil shortage has been a worldwide problem,while the demands for olefins,especially for propylene,has been growing steadily.The alternative ways for the production of ethylene and propylene from methanol,which can be obtained from coal and natural gas,have received much attention from academic and industrial fields in recent decades.The technologies of methanol to olefins （MTO） and methanol to propylene （MTP） are developed rapidly in recent years.This paper presents a review on the recent researches in this field,including the modifications on catalysts ZSM-5 and SAPO zeolites,advances in hydrocarbon pool mechanism,and the progress in the technology development and industrialization of MTO and MTP.
