硅基多孔材料改性固体吸附剂吸附CO_2研究进展
|
摘要
硅基多孔材料具有比表面积高、孔径可调控、合成原料廉价易得等优点。通过对其进行有机胺改性、金属负载改性、离子液体改性、表面活性剂改性等多种方式的修饰和改性,形成的硅基复合材料在CO_2捕集方面展示出广阔的应用前景。本文对近年来硅基改性固体吸附剂吸附CO_2的研究进行了综述,总结了各种硅基改性方法的优缺点。有机胺改性可分为浸渍改性和嫁接改性:浸渍改性具有操作步骤简单、CO_2吸附量大、能耗少等优点,但在用小分子胺改性时,存在吸附循环稳定性差的问题;嫁接改性具有稳定性高、胺利用率高的特点,但存在吸附量相对较少、能耗高的问题。金属改性和离子液体改性步骤简单,稳定性高,但其有效吸附量少。表面活性剂不仅改性方法简单,而且可有效提高CO_2吸附量,但二次加入表面活性剂会增加试剂消耗量。同时本文还指出了硅基改性固体吸附剂研究的不足之处,并初步展望了硅基改性固体吸附剂的发展方向。
Silica-based porous materials have advantages of high specific surface area, adjustable pore diameter and inexpensive synthetic raw materials. And they can be modified by a variety of ways to obtain the silica-based composites adsorbents which show great potential in CO_2 capture, such as amine modification, metal modification, ionic liquid modification and surfactant modification. In this paper, the recent research progress in modified silica-based porous materials for CO_2 adsorption is summarized.Amine modification can be divided into impregnation modification and grafting modification. Impregnation modification has advantages of simple operation steps, high adsorption capacity of CO_2, and low energy consumption. However, when the silica-based support is modified with small molecular amines, the stability of adsorbents is poor. Adsorbent by grafted modification has advantages of high stability and high amine utilization efficiency. But, the adsorption capacity is relatively small and the preparation process of the adsorbent has high energy consumption. Metal modification and ionic liquid modification have simple modification process and high stability, however, the adsorption capacity is low. Surfactant modification not only has simple modification process but also can increase the CO_2 adsorption capacity effectively, but the secondary addition of surfactant will increase the reagent consumption.Meanwhile, this paper also points out the shortcomings and the future development directions of silica-based modified adsorbent.
