摘　　要：甲醇制烯烃反应是基于甲醇为原料,生产以乙烯、丙烯为主的轻烯烃混合气的生产工艺,其主要产品是乙烯和丙烯。因此,如何提高乙烯和丙烯的收率具有重要意义。文章基于180万t/a甲醇制烯烃装置,研究了反应温度对产品组成的影响。结果表明:反应温度不同,烯烃各组分的选择性不同,适当的高温,有利于乙烯、丙烯等轻烯烃组分的生成。Methanol to olefins is a manufacturing technique based on methanol,which products are ethylene and propylene.Therefore it is important to syudy how to improving the yield.Based on the 1.8million t/a industrial MTO device,this paper research the effect of temperature.Results show that diffrent temperature make the diffrent yield.A appropriate high temperature is conducive to the production of light olefin components such as ethylene and propylene.
