采用不同方法制备了一系列Cu-Zn-Zr催化剂,借助XRD,BET,H_2-TPR和CO-TPD技术对催化剂进行了表征分析,评价了催化剂催化合成气合成低碳醇的催化性能。结果表明:添加有机助剂丙烯酰胺的并流沉淀法制备的Cu-Zn-Zr催化剂较其他方法具有晶粒细化,比表面积大,活性组分分散更均匀等优点,该催化剂催化性能较好,C_(2+)醇选择性较高。 A series of Cu-Zn-Zr catalysts were prepared by different methods. The catalysts were characterized by XRD, BET, H 2 -TPR and CO-TPD. The catalytic performance of the catalyst for the synthesis of lower alcohols was also evaluated. The results show that the Cu-Zn-Zr catalyst prepared by cocurrent precipitation method with organic assistant acrylamide has the advantages of grain refinement, large specific surface area and more uniform dispersion of active components than other methods. The catalyst has better catalytic performance , C_ (2+) alcohol selectivity higher.
