| 摘 要： | 使用自制的CuO-Al2O3催化剂对苯酚饱和活性炭进行非均相催化湿式氧化再生研究,系统观察了反应条件对非均相催化湿式氧化再生活性炭的影响.实验中得到非均相CuO-Al2O3催化湿式氧化再生活性炭的最佳条件为:反应温度210℃,反应时间60min,催化剂投加量25mg(以铜离子计),反应氧分压0.6MPa(25℃),投炭量15g(干炭量),加水量300mL.通过对催化剂进行X衍射分析,并对催化剂的稳定性进行实验,可以得出该催化剂在催化湿式氧化再生活性炭的过程中具有较好的稳定性.

| Abstract: | 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. |
