Research progress in CO2 adsorption on modified silica-based porous materials
摘要
Abstract
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 CO2 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 CO2 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 CO2, 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 CO2 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.关键词
