摘要

采用等体积浸渍法制备负载型CuO/TiO

催化剂，研究CuO含量、体积空速、O

含量、CO进口浓度及烟气含SO

时对催化剂CO氧化性能的影响，并对催化剂进行结构表征。结果表明：30wt%CuO/TiO

催化剂的CO催化氧化效率最佳，在10 000 h

-1

空速下180℃以上完全催化氧化CO

针对0.1～0.5vol%CO进口浓度在220～420℃实现95%以上CO转化效率。当烟气中通入SO

时，随着SO

浓度由0增至4 000 mg/m

30wt%CuO/TiO

催化剂在的CO转化率逐渐降低，SO

的存在抑制催化剂的活性。在150～180℃温度范围内进行30wt%CuO/TiO

催化剂的CO催化氧化本征反应动力学研究，实验及计算结果显示：30wt%CuO/TiO

催化剂表面的CO催化氧化可近似为一级反应，反应活化能为24.23 kJ/mol。
