摘要
二甲醚是良好的车用及民用清洁燃料,浆态床醇醚燃料技术已成为各国竞相研究开发的技术。综述了浆态床合成气制二甲醚工艺中的几种催化剂、反应动力学、气泡特征参数、气液传质系数及反应器模型等方面的研究进展。浆态床二甲醚合成工艺尚处于研究开发阶段,但将是二甲醚生产工艺的发展方向。亟待解决的问题主要有开发与液相介质相匹配的商业化新型浆态催化剂、固液分离技术及催化剂的循环再生工艺。
Dimethyl ether is used as an ideal civil and vehicle's clean fuel.Alcohol/ether synthesis in bubble column slurry reactor has become a hot spot for the research in the world.The progresses in the research for the catalysts,the reaction kinetics,the bubble characteristics,the gas-liquid mass transfer coefficient and the mathematical reactor model for the bubble column slurry reactor were reviewed.In research and development situation at present,direct synthesis process for the alcohol/ether fuel in the bubble column slurry reactor is the future development orientation for dimethyl ether production technologies.The present urgent problems to be solved mainly focused on the development of the distinctive commercial catalysts matching with the liquid,the separation of solid and liquid and the catalyst regeneration.
