甲醇制烯烃技术进展及与石油烃裂解制烯烃对比

摘要

The reaction mechanism of methanol to olefins and key technical issues were introduced in this paper. Comparisons were made between methanol to olefins and the traditional petroleum hydrocarbons cracking to olefins in terms of separation process, economics and environmental impacts. The result shows that methanol to olefins technology has the advantage of lower energy consumption, better environmental protection and less production cost. It is more competitive against the traditional petroleum route with reference to production cost.%介绍了甲醇制烯烃技术的反应机理和主要的技术问题,并将甲醇制烯烃技术与传统的石油烃裂解制烯烃技术在分离工艺和对环境的影响方面进行了对比.通过对比,表明甲醇制烯烃工艺在能耗、环保等方面与石油路线相比具有一定的竞争力.
