Progress in the One-Step Mass Production of Dimethyl Ether Using Circulating Slurry Reactors

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%.
