The latest development on amine functionalized solid adsorbents for post-combustion CO2 capture: Analysis review

Abstract

• Recent advances amine functionalized solid adsorbent for CO 2 capture are reviewed. • Solid amine adsorbents fabrication and modification route towards is emphasized. • Amine functionalized solid materials from the waste as competitive adsorbents. • Improved stability of solid amine adsorbents for CO 2 capture is analyzed. Global warming and associated global climate change have led to serious efforts towards reducing CO 2 emissions through the CO 2 capture from the major emission sources. CO 2 capture using the amine functionalized adsorbents is regard as a direct and effective way to reducing CO 2 emissions due to their large CO 2 adsorption amount, excellent CO 2 adsorption selectivity and lower energy requirements for adsorbent regeneration. Moreover, large number of achievements on the amine functionalized solid adsorbent have been recorded for the enhanced CO 2 capture in the past few years. In view of this, we review and analyze the recent advances in amine functionalized solid adsorbents prepared with different supporting materials including mesoporous silica, zeolite, porous carbon materials, metal organic frameworks(MOF) and other composite porous materials. In addition, amine functionalized solid adsorbents derived from waste resources are also reviewed because of the large number demand for cost-effective carbon dioxide adsorbents and the processing needs of waste resources. Considering the importance of the stability of the adsorbent in practical applications, advanced research in the capture cycle stability has also been summarized and analyzed. Finally, we summarize the review and offer the recommendations for the development of amine-based solid adsorbents for carbon dioxide capture.
