铜－锌系共沉淀催化剂制备与催化性能研究

研究了Ｃｕ－Ｚｎ系合成醇类催化剂的共沉淀方式、温度、陈化时间及对其母体（氧化物形式）的超声作用、共沉淀复盐形式的物理性质等对催化剂催化性能的影响。ＸＲＤ、ＩＲ及表面分析结果表明，共沉淀条件与催化剂复盐物及母体的物相、晶粒大小及其比表面密切相关。作者对催化剂复盐物、母体的物理性质以及催化剂的催化性能与共沉淀条件进行了关联和讨论。

Studies on preparation conditions and catalytic performances or copper-zinc coprecipitating catalysts

he effects of coprecipitating methods,temperatures, and aging time were investigated on the catalytic performances, such as the ultrasonic role of the precursors in oxide form, and the physical properties of coprecipitated complex salts, of Cu-Zn catalysts for synthesis of alcohols. The results of XRD,IR, and specific surface area analysis show that the coprecipitating conditions are closely related to the phases, crystal sizes and specific surface areas of complex salts and precursors of the catalyst. A correlation of the physical properties of complex salts and precursors of Cu-Zn catalysts and their catalytic performances with coprecipitating conditions is conducted and discussed.
