Abstract: In this study, the alumina supported copper oxide sorbents were prepared by the impregnation method.The influence of impregnation solution concentration was studied.Desulfurization- regeneration tests were made by using these sorbents.The surface microstructure changes of sorbents during desulfurization and regeneration were also analyzed.The results showed that 90% desulfurization efficiency was obtained by these sorbents and the performance of these sorbents was stable.

摘要： 采用浸渍法制备了铝基铜脱硫剂，考察了制备过程中浸渍液浓度对脱硫剂脱硫性能的影响，同时对制得的脱硫剂进行了循环烟气脱硫-再生实验，分析了脱硫剂的表面微观结构在脱硫和再生过程中的变化.实验和分析表明，制得的铝基铜脱硫剂具有较高的脱硫效率，使用该脱硫剂进行循环烟气脱硫的性能是稳定的.
