摘要

1.Introduction Ethylene and propylene are the cornerstones of the chemical industry,with more than 75%of chemical products as their downstream derivatives.They are conventionally produced via naphtha steam cracking and fluid catalytic cracking(FCC),in which oil is mainly used as feedstock.China,however,relies heavily on imports for crude oil.The Dalian Institute of Chemical Physics(DICP),together with China Petroleum&Chemical Corporation(Sinopec)Luoyang Petrochemical Engineering Company and SYN Energy Technology Co.,Ltd.,have developed a methanol-to-olefins technology—namely DMTO—which opens up an alternative path to synthesize light olefins from methanol,a platform chemical that can be readily derived from coal[1].As coal is relatively abundant in China,the success of DMTO is of practical significance in balancing the supply and demand of light olefins,reducing China’s dependence on imports for crude oil,and promoting national energy security.This report outlines the catalyst,fluidized-bed reactor,and process of DMTO technology,with an emphasis on the key technologies involved in commercial units and sustainable development for future applications.
