| 摘要: |
The direct oxidation of dimethyl ether (CH3OCH3，DME) to ethanol (CH3CH2OH) was carried out over WO3/HZSM-5 catalysts in a continuous flow type fixed-be d reactor.The effects of different zeolite types, WO3 loading and reaction temperature on the reaction were investigated . Our results showed that modi fication of HZSM-5 with 10% WO3 significantly improved the ethanol selectivity from 0.6% to 19.7%. The surface and structure of the catalysts were characterized by NH3-TPD, BET, XRD and in situ FT-IR.Ethanol can be mainly synthesized from DME direct oxidation under the cooperation of trifunctional reactive sites offered by WO3 modified HZSM-5 catalysts. |
