The synergy effect of for the dimethyl ether synthesis process coupling of reaction-reaction and reaction-heat transfer was studied. Via theoretical and experimental analysis, it was indicated that the synergy of the reaction-reaction is prominent and the synergy of reaction-heat transfer is also feasible. Due to the synergy effect, CO-rich synthesis gas can be used for the dimethyl ether synthesis and higher one-way CO conversion can be obtained. Recycle and compression of the unreacted synthesis gas can also be avoided. Accordingly, energy consumption and water gas shift reaction system would be saved, and the entire investment and production cost could be decreased.
