摘要
利用浸渍法制备催化剂CuO/γ-Al2O3、MnOx/γ-Al2O3、CuMnOx/γ-Al2O3,通过实验研究表明:CuMnOx/γ-Al2O3具有更高的催化活性,其T99比其他两种催化剂要低50℃以上。在焙烧温度300、400、500、600℃下制备CuMnOx/γ-Al2O3,比较其催化活性,发现在600℃制备的催化剂要比其他温度下制备的同等催化剂的催化活性高,证明了尖晶石结构在催化燃烧中起着很大的作用。
CuO/γ-Al_2O_3,MnO_x/γ-Al_2O_3 and CuMnO_x/γ-Al_2O_3 supported catalysts were prepared by impregnation.It was indicated by research that the T_ 99 of CuMnO_x/γ-Al_2O_3 catalyst was 50 ℃ lower than the other two catalysts.CuMnO_x/γ-Al_2O_3 catalyst was calcined under different temperatures of 300,400,500,600℃ and it was found that CuMnO_x/γ-Al_2O_3 catalyst calcined under 600℃ had higher catalytic activation.
