Aqueous solutions of 200-1000 mg/L of ammonia were oxidized in a trickle-bed reactor using Cu-activated carbon fiber (ACF) catalysts, which were prepared by incipient wet impregnation with aqueous solutions of copper nitrate that was deposited on ACF substrates. The results reveal that the conversion of ammonia by wet oxidation in the presence of Cu-ACF catalysts was a function of the metal loading weight ratio of the catalyst. The total conversion efficiency of ammonia was 95% during wet oxidation over the catalyst at 463 K at an oxygen partial pressure of 3.0 MPa. Moreover, the effect of the initial concentration of ammonia and the reaction temperature on the removal of ammonia from the effluent streams was also studied at a liquid space velocity of less than 3.0 h(-1).
使用通过将硝酸铜水溶液采用初湿浸渍法沉积在活性炭纤维（ACF）载体上制备的铜活化活性炭纤维（ACF）催化剂，在滴流床反应器中对浓度为200 - 1000 mg/L的氨水溶液进行氧化。结果表明，在铜 - ACF催化剂存在下通过湿式氧化法对氨的转化是催化剂金属负载重量比的函数。在463 K、氧气分压为3.0 MPa的条件下，在该催化剂上进行湿式氧化时，氨的总转化效率为95%。此外，还在液体空速小于3.0 h⁻¹的条件下研究了氨的初始浓度和反应温度对从流出物流中去除氨的影响。
