摘要: 研究了在催化湿式氧化体系中浸渍液浓度、焙烧时间和焙烧温度等制备条件对CuO/γ–Al2O3催化剂的催化活性和稳定性的影响;确定了最佳制备条件。结果表明:优化制备的CuO/γ–Al2O3催化剂,用于处理高浓度难降解的乳化液废水时,具有良好的催化活性,在200 ℃时反应2 h的CODCr去除率为88.4%,比未加催化剂的常规工艺提高了13.0%。

Abstract: This article systematically studied the influence of concentration of soaked liquid, the roasting time and the roasting temperature to activeness and the stable performance of CuO/γ–Al2O3 catalyst on system of catalyzed wet air oxidation, and the best preparation condition has been determined .The experimental results indicated that CuO/γ–Al2O3 catalyst was applied in the treatment of emulsification wastewater resulted in 88.4% CODCr removal after 2hrs’ oxidation at 200 ℃ (13.0%’s improvement compared to non-catalytic oxidation).
