摘 要：采用浸渍法制备了用于CO选择氧化的Ru-La203/Al203催化剂，研究了CO在Ru-La203/Al203催化剂床层上的CO选择氧化本征动力学．结果表明，在消除内外扩散的条件下，CO在Ru-La203/Al203催化剂床层的本征反应是一个表面反应控制的一级反应，反应的活化能为76.24kj/mol.
Abstract: Ru-La203/Al203 catalyst for the CO removal via selective catalytic oxidation was prepared by means of impregnation, and the corresponding intrinsic reaction kinetics was investigated. Experimental results show that the surface reaction on the catalyst bed plays the most important role in the control of reaction rate, and that, when eliminating the internal a
