| Abstract: | Loaded metal heterogeneous catalysts for catalytic wet air oxidation of eucalyptus CTMP simulated effluent were prepared by impregnating methods.Results showed that prepared CuO/γ-Al2O3 catalyst had the best catalytic activity under calcined temperature of 400℃,calcined time 4h,impregnating solution concentration 6% and impregnating time 5h.Removal efficiency more than 90% of tannic acid was achieved under reaction time 8h,pH of tannic acid 4.5,dosage of H2O2 and catalyst 0.2mL and 4g respectively. |
