The Dalian Institute of Chemical Physics （DICP） of CAS has developed the technology for manufacture of DME through two-step dehydration of methanol and catalytic distillation. Currently there are two processes for DME manufacture, i. e. the one-step method and the two-step method. The onestep process has not been realized in large scale production both at home and abroad because of the short run length of catalysts, complicated equipment,
