| 摘 要： | 采用浸渍法制备了商业硅胶负载聚乙烯亚胺(PEI)的CO2吸附剂,研究了该类吸附剂对CO2的吸附捕集性能,同时考察了尿素焙烧法对硅胶孔结构的影响。结果表明:尿素焙烧法可以有效调变商业硅胶的孔结构和比表面积;由硅胶为载体负载PEI后制备的吸附剂具有良好的CO2吸附性能,当PEI负载质量分数为30%时,CO2吸附量最大值可达93.4mg/g;并且在8次吸附-脱附循环测试中CO2吸附量无明显变化,表明该类吸附剂具有良好的CO2吸附再生稳定性能。

| Abstract: | A serial of polyethylenimine(PEI) functionalized commercial silica gel modified by urea calcination method were prepared by wet impregnation method,and their adsorption performances of CO2 as well as the effect of urea calcination method on the structure of the silica gel were investigated.The results showed that the pore structure and surface area of the silica gel could be adjusted efficiently by urea calcinations method,and the PEI functionalized silica gel adsorbents exhibited an excellent performance for CO2 adsorption.When the PEI loading amount of the adsorbent was 30% by mass,the adsorbent had the best CO2 uptake capacity,which was up to 93.4 mg per gram adsorbent.In addition,the PEI-impregnated silica gel showed stable adsorptiondesorption behavior during 8 consecutive test cycles. |
