摘要
采用涂覆-浸渍法制备了Pd/La2O3-CeO2-Al2O3/CC催化剂,测定了其对低浓度甲烷催化燃烧活性。试验表明,Pd/La2O3-CeO2-Al2O3/CC催化剂具有良好的催化活性,Pd负载量大的催化剂活性越好,La2O3对催化剂稳定性有帮助,CeO2的加入可以提高催化活性,空速为10000h-1时,0.5%Pd催化剂的T10为309℃、T90为432℃。
Pd / La2O3-CeO2-Al2O3/CC catalyst was prepared by the method of coating-impregnation. And the catalytic oxidation activity was also determined. The experiment verified that Pd/La2O3-CeO2-Al2O3/CC catalysts have high activity. The activity is higher if the catalyst loaded with more Pd and La2O3 improves the stability of the catalyst, and CeO2 can improve the catalytic activity. Catalyst 0.5%Pd＇s T10 is 309℃ and its T90 is 432℃ when the space velocity is 10000h-1.
