cu修饰的fe2o3/al2o3氧载体的循环反应稳定性研究
, PP. 121-128
Keywords: 化学链燃烧,氧载体,稳定性,fe2o3,cu
Abstract:
？采用冷冻干燥法制备了经cu修饰（10%）的fe2o3/al2o3氧载体。利用热重分析仪分别在850、900和950℃等温环境下，使氧载体交替接触还原气体和氧化气体，来模拟氧载体在化学链燃烧中的循环过程。结果表明，经cu修饰的fe2o3/al2o3氧载体在850和900℃下的等温循环过程中反应性能都很稳定，在950℃时的循环反应前期有微量烧结，但在循环后期反应性能也很稳定。随着反应温度的升高，氧载体氧化速率增大，还原速率和载氧率先减小后增大。与未经修饰的fe2o3/al2o3氧载体相比较，在900℃下作等温循环实验，经cu修饰的fe2o3/al2o3氧载体具有较高的载氧能力和还原速率，但氧化速率较低；两者都具有较好的循环稳定性。
