| 摘 要： | 选取球状堇青石蜂窝陶瓷作为催化剂基体,制备了CuMn/ZrAlTi-堇青石蜂窝陶瓷催化剂,采用XRD、X射线光电子能谱(XPS)、比表面积测定(BET)等分析方法对其进行了表征,测定了其催化湿式氧化含酚废水的活性及催化剂抗压强度、脱落率、Cu2+溶出浓度等性能指标.实验结果表明:CuMn/ZrAlTi-堇青石蜂窝陶瓷催化剂在反应温度220℃、压力5 MPa、搅拌速率为600 r/min时,催化湿式氧化反应300 min,COD去除率可达94.6％;球状CuMn/ZrAlTi-堇青石蜂窝陶瓷催化剂具有强度高、易装填、易更换、脱落率低等特点,Cu2+溶出浓度低于国家排放标准,适合工业化处理含酚废水.

| Abstract: | CuMn/ZrAlTi-cordierite honeycomb ceramics catalyst was prepared using spherical cordierite honeycomb ceramics as catalyst carrier,and was characterized by XRD,XPS and BET.Its catalytic activity,compressive strength and Cu2+ leaching concentration in phenol wastewater treatment were determined.The experimental results show that:Under the conditions of reaction temperature 220℃,reaction pressure 5 MPa,stirring speed 600 r/min and reaction time 300 min,the COD removal rate can reach 94.6%;With the features of high strength,easy loading and replacement,low expulsion rate and low Cu2+ leaching concentration(which is lower than the national discharge standard),the spherical CuMn/ZrAlTi-cordierite honeycomb ceramics catalyst is applicable to industrial treatment of phenol wastewater. |
