【摘要】 考察了反应温度、反应压力、反应气量、空速以及贵金属担载量等因素对Ru/TiO2催化剂催化湿式氧化法处理H 酸废水处理效果的影响.此外还利用X 荧光光谱(XFD)和X 射线粉末衍射(XRD)等表征手段研究了催化剂TiO2载体的杂质含量和晶型.结果表明:随着催化剂上活性组分担载量的增加,催化剂的催化活性逐步提高.在温度为240℃、压力为6.0MPa、空速为2.5h-1、气量为150mL/min的反应条件下,经过担载量为w(Ru)=3%的Ru/TiO2催化剂的催化湿式氧化处理,模型废水中的COD去除率可达到99.8%.更多还原

【Abstract】 The effect of factors such as reaction temperature, pressure, feed of air, space velocity and Ru loading on the reduction rate of COD was investigated. Moreover, XFD and XRD were employed to study crystal form and composition of TiO2 support. It was found that the catalytic activity increases with increasing Ru loading, and the reduction rate of COD is 99.8% at 240 ℃, 6.0 MPa, feed of air 150 mL/min, S.V. 2.5 h-1 and Ru loading of 3%.更多还原
