| 摘 要： | 将丙烯酰胺(AM)改性的四乙烯五胺(TE-PA)负载到介孔材料孔道内,形成氨基改性的CO2吸附材料。利用X射线衍射(XRD)、氮气物理吸附-脱附(BET)、红外等方法对样品进行了表征。通过动态吸附法研究了材料的CO2吸附和脱附性能,并与TEPA负载的吸附材料进行了比较。研究结果表明,在制备介孔分子筛MCM-41的过程中得到的一种结构规整度低的材料对TEPA-AM具有较好的分散性能,经过TE-PA-AM修饰的该材料表现出良好的CO2吸附性能,当TEPA-AM负载量达60%,该材料的吸附能力达到159.1mg/g;经过12次循环使用吸附量不下降。

| Abstract: | CO2 adsorption materials were prepared through loading AM-modified tetraethylenepentamine(TEPA) in mesoporous silica pore channels.The materials were characterized by XRD,N2 physisorption techniques(BET) and FT-IR.The capacity of CO2 adsorption and desorption were measured and evaluated by comparison with TEPA-impregnated material.The results showed that a novel mesporous material with low structural order could disperse TEPA-AM well.Its CO2 sorption capacity reached up to 159.1mg/g with 60% TEPA-AM loading.The hybrid material exhibited satisfactory performance during 12 turnovers. |
