| 摘 要： | 采用浸渍法制备La_(0.75)K_(0.25)Mn_(0.95)Cu_(0.05)O_3/CeO_2钙钛矿型复合氧化物催化剂(负载质量分数分别为10%、20%、30%、50%和100%),利用XRD、FT-IR及UV-Vis DRS表征手段对制备的催化剂进行表征,以C_2H_2为还原剂,考察该氧化催化剂净化FCC再生烟气的性能。结果表明,制备的系列氧化催化剂存在明显的钙钛矿结构,并且La_(0.75)K_(0.25)Mn_(0.95)Cu_(0.05)O_3/CeO_2(50%)催化剂的氧化活性最高。

| Abstract: | Perovskite-type composite oxide catalystsLa0.75 K0.25 Mn0.95 Cu0.05 O3/Ce02 with loading mass fraction of 10% ,20% ,30% ,50% and 100% were prepared by impregnation method, and characterized by using XRD, FF-IR and UV-Vis DRS techniques. The performance of the catalysts for FCC regenerated flue gas purification were investigated using C2 H2 as the reducer. The results showed that the as-prepared oxidation catalysts had the obvious structures of perovskite, andLa0.75 K0.25 Mn0.95 Cu0.05 O3/Ce02 （ 50% ） catalyst exhibited the best catalytic activity. |
