摘　　要：　介绍了清华大学与重庆英力燃化有限公司合作开发的燃料级二甲醚合成中试研发进展。采用新型循环浆态床反应器一步法合成二甲醚技术取得了实质性突破,并获得了良好的中试结果:CO单程转化率达到60%以上,DME选择性达到94%,明显优于APCI和NKK的浆态床二甲醚合成工艺。The progress in developing one-step technology for dimethyl ether (DME) mass production by Tsinghua Univer-sity and Chongqing Yingli Fuels & Chemicals Co. Ltd. has been introduced. The new process, using a circulating slurry reactor,acquired a substantial breakthrough in the industrialization of the one-step DME technology and obtained approving results inthe pilot plant: the once-through CO conversion reached to over 60% and the selectivity of DME over 94%.
