摘要
煤制烯烃技术是连接煤化工与石油化工,实施石油替代战略、保障能源安全的重要战略方向。甲醇制烯烃(MTO)是实现煤制烯烃的关键核心技术,不仅涉及第一个碳碳键形成和碳链定向增长控制等科学问题,还具有反应速度快、转化率高、强放热等反应和工艺特征。发展甲醇制烯烃技术必须解决与反应原理、催化剂、反应工艺相关的一系列科学和技术难题。中国科学院大连化物所在MTO催化剂、MTO反应和MTO过程开发方面进行了长期的研究。合作开发了甲醇制烯烃(DMTO)技术,完成了世界首次万吨级甲醇制烯烃工业性试验和世界首套煤基甲醇制取烯烃工业装置。截止2015年,已有9套采用DMTO技术的甲醇制烯烃工业装置实现了成功运转。对甲醇制烯烃反应机理的理解是DMTO过程发展的基础,本文主要针对大连化物所的研究结果对MTO机理研究进展进行了更新和总结。内容包括:直接反应机理的特点及验证,各种不同分子筛催化体系烃池物种的捕获、鉴定及作用机理研究,分子筛催化剂失活机理研究,及反应诱导期现象和动力学研究等。给出了MTO反应网络模型。希望对于MTO技术的进一步发展具有一定的指导意义。
Methanol-to-olefin reaction is one of the most important and innovative reaction route connecting coal-based chemicals and petrochemicals production and also provides an alternative way to produce backbone chemicals from some abundant non-oil resources,such as coal or natural gas.The reaction involves the formation of C-C bond from C1 reactant as initial step followed by many possible reaction paths,giving a complicated reaction network,which makes the selectively control of the reaction path for target products generation to be a great challenge.The long term and continuous research effort of the scientists in DICP made many outstanding contributions to this process,from fundamental findings to DMTO technology inventions for coal-to-olefins industry.In August,2010,the world's first commercial application of MTO process(DMTO),with a production capacity of 600,000 ton of light olefins per annum,was proved to be completely successful in Baotou,China.This presentation gives a summary of the recent progress on MTO reaction mechanism researches.
