| 摘 要： | 通过自行设计制作的滴流床反应器,研究了苯酚在以CuO/γ-Al2O3为催化剂的催化湿式氧化反应.结果表明,在相对温和的操作条件(温度180 ℃,压力3 MPa,液相流量1.668 L·h-1,气相流量160 L·h-1)下,苯酚的去除率均达到90%以上.苯酚的降解曲线与自催化反应的S型曲线类似,符合自由基链反应机理.所建立的活塞流拟均相反应器模型能很好地拟合苯酚催化湿式氧化反应过程.还研究了苯酚初始浓度、苯酚水溶液流量及反应温度对反应结果的影响.

| Abstract: | By using a trickle bed reactor which was designed by the authors, the catalytic wet air oxidation reaction of phenol on CuO/gamma-Al2O3 catalyst was studied. The results showed that in mild operation conditions (at temperature of 180 degrees C, pressure of 3 MPa, liquid feed rate of 1.668 L x h(-1) and oxygen feed rate of 160 L x h(-1)), the removal of phenol can be over 90%. The curve of phenol conversion is similar to "S" like autocatalytic reaction, and is accordance with chain reaction of free radical. The kinetic model of pseudo homogenous reactor fits the catalytic wet air oxidation reaction of phenol. The effects of initial concentration of phenol, liquid feed rate and temperature for reaction also were investigated. |
