摘要:
将吸附材料分子筛粉末、吸波材料碳化硅粉末以及催化活性组分铜（Cu）、锰(Mn)、铈(Ce)盐溶液完全混合，通过制粒、煅烧后制得复合载体负载型催化剂；微波辐照条件下，应用该催化剂进行了甲苯废气的催化氧化性能试验研究．研究表明，复合载体负载型催化剂的优化制备条件为：高岭土为粘合剂，掺入3%的碳化硅，铜锰质量比为1︰1（各5 %负载量）， 铈的掺杂量为1.67 %，焙烧温度为500 ℃，焙烧时间为8h. 反应温度210 ℃下，优化制备的复合载体催化剂催化氧化甲苯的转化率达95 %，表现出良好的低温活性和催化氧化性能．
Abstract:
Molecular sieve powder, silicon carbide powder and copper (Cu), manganese (Mn) and cerium (Ce) saline solutions were mixed completely, and then pelletized and calcined to prepare composite carrier loaded Cu- Mn-Ce catalyst. The catalyst prepared was applied to oxidize gaseous toluene under microwave irradiation and continuous flow mode, and catalytic performance was mainly checked. The research showed that optimization preparation conditions of the catalyst were kaolin as the binder, 3% silicon carbide doping amount, 1:1 mass ratio for Cu and Mn and 5% loaded amount respectively, 1.67% cerium doping amount, 500 ℃ calcination temperature and 8 h roasting time. Under the reaction temperature of 210 ℃, the removal efficiency of toluene reached 95% by microwave assisted catalytic oxidation using optimized catalyst. It indicated that the prepared catalyst owned good catalytic activity and performance under low temperature.
