固态胺吸附剂分离密闭空间低浓度CO_2的研究进展

DEVELOPMENT OF AMINE-BASED SOLID SORBENTS FOR SEPARATION OF LOW-CONCENTRATION CO_2 FROM CONFINED SPACE

近年来,密闭空间低浓度CO2的吸附分离技术是研究热点,固态胺吸附剂因其再生能耗低、选择性高、易操作等优点受到广泛关注。综述了固态胺吸附剂常见的制备方法、表面改性剂和多孔材料载体,同时综合评价CO2的吸附效率,最终展望了固态胺的发展趋势。

Recently,adsorption and separation technology for low-concentration CO2 from confined space have been attracted great attentions.Amine-based solid sorbent is considered as one of the most important materials since it is low in energy consumption,high in selectivity,and simple in operation.The preparation method,additives of organic amine and porous substrates for synthesis of amine-based sorbent were reviewed,furthermore the adsorption efficiencies were evaluated and the development trend of amine-based solid sorbents was also prospected.
