| 摘 要： | 分别用草酸盐胶态共沉淀法和碳酸钠并流共沉淀法制备了Cu-Mn/ZrO2催化剂，发现催化剂的前驱物及其制备的均匀程对催化剂的反应性能影响很大，均匀沉淀法促进了催化剂的分散及组元之间的相互作用，明显提高了CO加氢合成甲醇的反应活性。三种元素之间的协同效应对合成甲醇反应的活性有决定性的作用，同时发现反应可能是一个受扩散影响较大的过程。

| Abstract: | Cu-Mn/ZrO 2 catalysts have been prepare by oxalate gel coprecipitation as well as Na 2CO 3 coprecipitation methods, and the catalysts obtained behave remarkably different activity and selectivity for CO hydrogenation to methanols ynthesis. The catalysts prepared by oxalate gel coprecipitation perform a higher activity, its surface area and particle size are lower than those of Na 2CO 3 coprecipitation prepared catalysts. The XRD patterns exhibit a kind of complex oxide that only exists in Na 2CO 3 coprecipitation prepared catalysts. The interaction among Cu,Mn and Zr is thought to be important in the characteristics of catalysts. |
