[Study on activated carbon regeneration by heterogeneous catalytic wet oxidation]

The CuO-Al2O3 catalyzer was used to heterogeneous catalytic wet oxidation regeneration of activated carbon, which adsorbed the phenol saturated. The study found the effect of reaction factors on activated carbon regeneration by heterogeneous catalytic wet oxidation. And the optimum reaction condition was reaction temperature 210 degrees C, reaction time 60 min, catalyzer dosage 25 mg (calculated by Cu), reaction oxygen pressure 0.6 MPa at 25 degrees C, carbon 15 g (dry carbon), distilled water 300 mL. It was found that the catalyzer had good stability in this experiment by using X-rey radiation analysing catalyzer and experiment on catalyzer stability.
