Abstract

The single-step synthesis of dimethyl ether from syngas has been simulated thermodynamically with the advanced process simulator Aspen plus.The influences of temperature,pressure,component of syngas,carbon dioxide content and water content in feed gas on the conversion of CO,selectivity and yield to dimethyl ether were discussed.The results of simulation were in good agreement with the experimental dates taken from a fixed micro-reactor in literature.
