摘　　要：使用不同的共沉淀方法制备了CuO-ZnO/Al2O3催化剂,利用氮气物理吸附脱附的方法对其比表面积和孔结构特征进行了分析,并在实验室小型固定床反应器上对所得催化剂的醋酸仲丁酯加氢性能进行了考察,结果表明,采用分步沉淀法制备的CuO-ZnO/Al2O3催化剂在醋酸仲丁酯加氢制仲丁醇反应中具有更好的加氢性能。CuO-ZnO/Al2O3 catalysts were prepared by different coprecipitation methods.The specific surface area and pore structure of the catalysts were analyzed by physical adsorption and desorption of nitrogen.The hydrogenation performance of the catalysts for sec-butyl acetate was investigated in a laboratory fixed-bed reactor.The results showed that the catalysts were precipitated step by step.The prepared CuO-ZnO/Al2O3 catalyst has better hydrogenation performance in the hydrogenation of sec-butyl acetate to sec-butanol.
