CO在Cu-Mn催化剂上催化氧化本征反应动力学研究

本文采用共沉淀法制备了用于低温CO催化氧化的Cu-Mn催化剂，对其进行了XRD分析和SEM表征，结果表明非晶态催化剂在室温下显示出良好的氧化活性。在50～80℃范围内研究了CO在所制备Cu-Mn催化剂床层上的催化氧化本征反应动力学，同时测定了CO在Cu-Mn催化剂上的催化反应等温线。结果表明,CO在Cu-Mn催化剂床层上的本征反应是一个表面反应控制的一级催化反应,反应的活化能是43.0kJ.mol-1。

The intrinsic kinetics of CO oxidation on the Cu-Mn catalyst

The Cu-Mn catalyst was prepared by co-precipitation and characterized by means of XRD and SEM, the analytical results indicated the amorphous catalysts had excellent activity for CO oxidation at room-temperature. The intrinsic reaction kinetics for CO oxidation on copper-manganese catalyst in the temperature of 50℃ to 80℃was also investigated, the conversion of CO at different reaction temperature on the catalyst bed was measured, the experimental results show that in the experimental area, the surface reaction on catalysts played the most important role in the reaction rate control, and the catalytic oxidation reaction of CO was a first-order catalytic reaction. The reaction activation energy of CO on Cu-Mn catalyst bed was 42.963kJ.mol-1.
