摘要
制备了载体为TiO2,活性组分为Ru(w=0.5%)和Ce,Mn的氧化物的催化湿式氧化法催化剂.制备中运用了Ce,Mn硝酸盐对载体的浸渍法预处理和表面纳米化技术的组合.研究了对模拟废水的催化湿式氧化分解的催化活性,COD去除率近70%,NH3-N去除率87.9%.
The study of preparation of Ru-CeO_2-MnO_2/TiO_2 catalyst for catalytic wet air oxidation process the catalyst in which active components were Ru(0.5%),Ce and Mn oxides supported on TiO_2 was prepared with technique of surface nanometerizing.The catalyst has been applied in catalytic wet air oxidation (CWO) process of simulated wastewater containing succinic acid and (NH_4)_2SO_4.It was found that its catalytic activity was acceptable by the dterminations of COD and T_N of the simulated wastewater.The ratio of removing COD was about 70%,and vatio of removing NH_3-N was 87.9%.
