Abstract：Dimethylether，as themost promisingalternative togasolineanddieselfuel，hasbecomeakeyresearch focus foran ncreasingumberofscholars.Itsprospectsare exceptionallbroad，bothinterms ofenvironmentalbenefits and socialimpact.In this paper，the REquil balanced reactor inAspen Plus wasusedto simulate dimethylether synthesis. The optimal carbon-to-hydrogen volumeratio，mostsuitable physical propertymethd，and idealreactionconditions for producing dimethyl ether via aone-step syngas process were investigated.The results indicated that the optimalcarbonto-hydrogen volume ratio was 2.05， the optimal reaction temperature was 255°C ， and the optimal reaction pressure was 7MPa . Additionally， the water vapor content in the reaction feed should be minimized as much as possible.
