摘要
由温室效应带来的全球变暖等一系列环境危害已受到越来越多的关注,CO2是对温室效应贡献最大的气体且用途广泛,因此,其控制减排及再利用尤为重要。综述了近年被广泛研究的CO2多孔吸附剂的发展状况,详尽阐述了沸石、多孔炭、有机金属骨架(MOFs)和多种介孔吸附剂的优缺点及其改性方法,同时比较了这几种多孔吸附剂改性前后的特性及其对CO2的吸附效果。并且展望了CO2吸附剂的发展前景,为新型高效CO2吸附剂的研发提供了参考。
A series of environmental harm caused by the greenhouse effect,such as global warming,has attracted more and more attention,CO2 not only has the greatest to greenhouse effect,but has a wide range of uses,so controlling the emission of CO2 as well as the reusing of it is pretty important.This paper describes the capture and the separation technology of CO2,and emphatically reviews the development of CO2 porous adsorbent which has been extensively studied in recent years.The advantages,disadvantages and modification method of zeolites,porous carbon,Metal-Organic Frameworks(MOFs)and a variety of mesoporous adsorbents were discussed thoroughly,the characteristics and CO2 adsorption effect of these porous adsorbent were also compared between before and after modification.At the end of the paper,the development prospects of CO2 separation is proposed,which provides a reference for the development of new efficient CO2 adsorbent.
