Studies on copper catalysts for wet air oxidation of high concentration coking-plant wastewater

通过共沉淀法制备了Cu系催化剂 ,用于催化湿式氧化处理高浓度焦化废水。结果表明 ,铜氧化物催化剂的催化活性明显优于其它过渡金属氧化物 ,优化催化剂的设计和制备方法 ,可有效地控制Cu2 +的溶出 ,克服Cu2 + 的溶出问题 。

Copper catalysts were prepared with the method of the codeposition,and applied to the catalytic wet oxidation (CWO) treatment of high concentration coking plant wastewater.The results show that the activity of copper oxide catalysts was better than that of other transition metal oxides.Some measures of controlling the leaching of Cu 2+ , such as changing the reaction condition and optimizing the design and make of Catalysts, were discussed in the paper The catalysts would have wide application prospect if the leaching could be controlled.
