摘要
采用共沉淀法制备了一系列过渡金属(Cu,Mn,Co,Fe,Ni,Cr)掺杂的ZrO2催化剂,XRD表征.表明属于立方型ZrO2结构.在250 mL间歇式反应釜中,反应温度150℃,初始压力为3.5 MPa,反应时间90 min的条件下,对苯酚(2.1 g/L,COD质量浓度为5 000 mg/L)的催化湿式氧化结果为:COD去除率为12.6%~83.1%.其催化活性顺序为:Cu-ZrO2>Mn-ZrO2>Co-ZrO2>Ni-ZrO2>Cr-ZrO2>Fe-ZrO2.研究了催化剂Cu-ZrO2在不同反应条件下对COD去除率的影响.
A series of transition metal(Cu,Mn,Co,Cr,Fe and Ni) doped ZrO_2(cubic) catalysts(transition metal/Zr mole ration=0.25) were prepared by co-precipitation.The doping of transition metal in ZrO_2 was confirmed by XRD.Degradation of phenol(COD concentration is 5?000?mg/L) in aqueous solution were carried out using a slurry autoclave at t=150?℃ and initial pressure p=3.5?MPa.COD removal for phenol was at the range of 12.6%—83.1% for different catalysts in 90?min.The phenol combustion performance of catalysts was...
