| 摘 要： | 以Cu-ZnO-Fe2O3-ZrO2作为甲醇合成活性组分并以HZSM-5作为甲醇脱水活性组分用3种不同的方法合成了催化剂,对催化剂进行了XRD和BET表征.研究了3种合成方法对于生物质合成气一步法制二甲醚Cu-ZnO-Fe2O3-ZrO2/HZSM-5催化剂催化性能的影响,结果表明,合成方法对于活性组分的分散度有很大的影响,从而进一步影响催化剂对于该反应的催化活性及目标产物的选择性.

| Abstract: | Three catalysts were synthesized using Cu-ZnO-Fe2O3-ZrO2 as methanol synthesis component and HZSM-5 as methanol dehydration component.The catalysts were characterized using X-ray diffraction（XRD）,and Brunauer-Emmett-Telle（r BET）surface area techniques.Synthesis methods on catalytical performance of catalysts for direct synthesis of dimethyl ether from bio-syngas were studied.The results show that synthesis methods have great impact on the dispersity of active components of the catalysts,and then affecting the conversion of CO and selectivity of DME for this reaction. |
