Abstract: | Cu-Co/C (heterogeneous) and CuSO4 (homogeneous) were used as catalysts for wet air oxidation to remove nitrogen containing toxic organic compounds from wastewater. For this purpose, a model compound, pyridine, was treated in a high-pressure batch autoclave at mild conditions of temperature and pressure. Copper and cobalt are relatively inexpensive catalytic material and have shown higher conversion efficiencies. Both CuSO4 and Cu-Co/C have optimum activity at an initial pH 4 of the pyridine solution. After 2 h of reaction time, % conversion with CuSO4 (75.1 %) was more in comparison to Cu-Co/C (71.8 %) using 5 mg/l catalyst concentration at 160 oC and 9 bar total pressure. |
