摘要

Abstract

One-step synthesis of DME (dimethyl ether) from syngas on hybrid catalyst is studied.In the experiment

the effects of variables including composition of feed gas

temperature and pressure are studied under the condition as follows:the catalyst was composed of C302 methanol synthesis catalyst and CM-3-1 methanol dehydration catalyst (mixing ratio 1∶1).Liquid paraffin is used as inert solvent.The reaction temperature is in the range of 230-270℃ and the pressure is in the range of 3.0-5.0MPa.It turns out that with the temperature and pressure increasing the conversion of carbon

the selectivity and production rate of dimethyl ether increase

while the selectivity and production rate of methanol decrease.Furthermore

both the conversion of carbon and the selectivity of dimethyl ether are high for the syngas of appropriate CO 2.
