| Abstract: | The physicochemical properties of dimethyl ether（DME）, its application, possible reaction mechanisms and kinetics models for one-step syngas-to-dimethyl ether conversion were reviewed. The active components in the catalysts for either methanol synthesis or methanol dehydration were discussed. It was shown that CuO/ZnO/Al2O3 exhibited higher activity and stability for methanol synthesis and γ-Al2O3 and zeolites had higher activity for methanol dehydration. The methods for preparation and modification of catalysts were outlined, too. |
