| Abstract: | The study of preparation of Ru-CeO2-MnO2/TiO2 catalyst for catalytic wet air oxidation process the catalyst in which active components were Ru (0.5%),Ce and Mn oxides supported on TiO2 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 (NH4)2SO4.It was found that its catalytic activity was acceptable by the dterminations of COD and TN of the simulated wastewater.The ratio of removing COD was about 70%,and vatio of removing NH3-N was 87.9%. |
