| 摘 要： | 采用浸渍法制备了以FeOx和MnOx混合氧化物为活性组分,堇青石蜂窝陶瓷为载体的有机废气催化燃烧催化剂,以甲苯作为探针反应物测定该类催化剂的催化燃烧活性。考察了Fe与Mn物质的量比、焙烧温度及其改性载体等因素对甲苯催化燃烧性能的影响,深入进行了XRD和BET表征与分析。实验结果表明:Fe/Mn物质的量的比为4∶1,质量负载量为10%,焙烧温度为500℃,并经γ-Al2O3涂层改性的催化剂具有最佳的催化燃烧活性。

| Abstract: | A series of Fe-Mn-O complex oxides catalysts supported on cordierite are prepared by impregnation method.The structure of the catalysts is characterized by XRD and BET measurements.Catalytic performance of the catalysts is investigated by catalytic combustion of toluene.The effects of the preparation parameters including the Fe/Mn ratio,the calcinations temperature and modified carrier are studied.The results show that the catalyst with 10% load of Fe-Mn,4/1 molar ratio of Fe/Mn,500℃ of roasting temperature and modification by γ-Al2O3 coating exhibits the highest catalytic performance. |
