摘　　要：采用浸渍法分别将二乙烯三胺(DETA),二乙醇胺(DEA),乙醇胺(MEA),三乙烯四胺(TETA),羟乙基乙二胺(AEE)负载到MCM-41介孔硅材料上,制成各种吸附剂,考察不同胺负载量的吸附剂对CO2的吸附和再生性能;结果表明质量负载量为50%的AEE/MCM-41吸附效果最佳,在80℃下具有很好的再生性能。The solid amines was prepared with MCM-41 type mesoporous silica,which was modified by Diethylenetriamine(DETA),Diethanolamine(DEA),Monoethanolamine(MEA),Triethylenetetramine(TETA),β-hydroxyethylenediamine(AEE) using post-synthetic impregnation.The adsorption behavior of CO2 on MCM-41 was investigated using an adsorption column.At different amine load of adsorbents to study CO2 absorption and regeneration performance.The results clearly indicated that the adsorption activity of MCM-41 modified by AEE with 50 wt% showed the best performance.And in 80 ℃ which has the good regeneration performance.
