摘要 采用等体积浸渍法制备了一系列PdCl2-CuCl2/γ-Al2O3催化剂,以CO催化氧化作为目标反应,分别考察了活性组分负载量、反应气浓度及湿度、反应温度对催化剂性能的影响。结果表明:水气的存在是该催化反应能够发生的前提;反应温度的变化对催化效能影响较小,而反应气浓度变化对催化性能影响显著;实验条件下负载2%Pd-2%Cu的催化剂效果最好。室温下,该催化剂在相对湿度为50%~60%、体积空速为30000h-1,对2.23×10-4mol/L的CO转化率可达90%以上。 A PdCl2-CuCl2/γ-Al2O3 catalyst has been synthesized by the method of incipient impregnation. The catalyst loading,Pd/Cu ratio,CO concentration,amount of moisture and reaction temperature were varied in order to identify the optimum reaction conditions. The results showed that:the presence of water vapor was a prerequisite for the catalytic reaction,the reaction temperature had a limited impact on the catalytic performance,and the reactive gas concentration significantly affected the catalytic performance. A 2% Pd-2% Cu catalyst showed 90% conversion for oxidation of 2.23×10-4 mol/L CO with a relative humidity of 50%-60% and a volume space velocity of 30000 h-1 at room temperature.
