The method comprises the step of preparing dimethyl ether from a synthesis gas in the presence of an acid catalyst and a methanol synthesis catalyst, wherein the carbon dioxide generated in the synthesis process of dimethyl ether is converted into carbon monoxide with the surplus hydrogen circulated in a reaction system in the presence of a catalyst for reverse water gas shift reaction and the converted one is recirculated into the synthesis process of dimethyl ether. Preferably the reverse water gas shift reaction is carried out at a temperature of 400-1,200 deg.C and at a pressure of 1-100 atm in the presence of a catalyst. Preferably the catalyst is the ZnO supported or coprecipitated in at least one oxide selected from Cr2O3, Al2O3, ZrO3, MgO, MnO and SiO2, and the content of ZnO is 10-90 wt% based on the total catalyst.
