Abstract: Influence of reaction temperature, pressure and space velocity on the direct synthesis of
dimethyl ether (DME) from syngas is studied in an isothermal fixed-bed reactor. The
catalyst is a physical mixture of C30 copper-based methanol (MeOH) synthesis catalyst and
ZSM-5 dehydration catalyst. The experimental results show that the chemical synergy between
methanol synthesis reaction and methanol dehydration reaction is evident. The conversion of
carbon monoxide is over 90%.

Key words: dimethyl ether, chemical synergy, methanol dehydration, syngas
