纤维素气凝胶负载有机胺强化CO_2吸附的研究
|
摘要
以氯化1-丁基-3-甲基咪唑离子液体(BMIMCl)为纤维素溶解介质,通过冷冻干燥法制备出具有三维孔道结构的纤维素气凝胶,并利用浸渍法分别将二乙醇胺(DEA)、二乙烯三胺(DETA)、多乙烯多胺(PEPA)和聚乙烯亚胺(PEI)负载于纤维素气凝胶上,以强化其CO_2吸附性能。采用FT-IR、TG/DTG、SEM、N_2等温吸脱附等方法对材料进行了表征,并采用自制静态吸附装置对负载前后气凝胶的CO_2吸附性能进行了测试。结果表明,虽然有机胺负载的纤维素气凝胶的比表面积和孔容有一定程度的下降,但负载有机胺能显著提高纤维素气凝胶对CO_2的吸附量,其中负载DEA时效果最好。CO_2吸附量随DEA负载量的增加呈现先增大后减小的趋势,当DEA加入质量分数为40%时气凝胶对CO_2吸附量最大,在313.15K、绝对压力190kPa下,达到1.99mmol/g,而相同条件下,未浸渍的纤维素气凝胶吸附量仅为0.55mmol/g。拟合结果表明,CO_2在有机胺负载的纤维素气凝胶上的吸附行为符合Langmuir单分子层吸附模型。
Aerocellulose with three-dimension pore structure was prepared by freeze-drying method through dissolving cotton cellulose in 1-butyl-3-methylimidazolium chloride(BMIMCl). The prepared aerocellulose was functionalized with diethanolamine(DEA), diethylenetriamine(DETA), polyethylene polyamine(PEPA) and polyethylenimine(PEI), respectively, by impregnation method to intensify the ability of CO_2 adsorption. The amine-functionalized aerocelluloses were characterized by FT-IR, TG/DTG, SEM and N_2 adsorption-desorption, and their CO_2 adsorption performances were tested in a self-made static adsorption device. The results showed that although the specific surface area and pore volume of the amine-functionalized aerocelluloses decreased, the loading of organic amine could significantly increase the adsorption capacity of aerocelluloses to CO_2, and the loading of DEA had the best effect. The adsorption capacity increased first and then decreased with the increase of DEA loading, and the highest CO_2 adsorption capacity reached 1.99 mmol·g~(-1) at DEA loading of 40% by mass, 313.15 K and 190 kPa. Whereas, the adsorption capacity of pure aerocellulose was 0.55 mmol·g~(-1) under the same conditions. The fitting results indicated that the behavior of CO_2 adsorption on the aminefunctionalized aerocellulose accords with the Langmuir monolayer adsorption model.
