Abstract: The methanol-to-olefin (MTO) technology offers an alternative for the conversion of coal to light olefins by using coal methanol as raw material. This paper introduces the development, processing and present status of methanol-to-olefins technology both at home and abroad. It also covers the progress on the catalysts research and reaction mechanism of MTO. The paper also analyzes the application and the restriction of MTO technology and provides some prospect according to the actual conditions in China.
Key words: methanol-to-olefin(MTO); technology; catalysts
