高效节能的CO2捕获吸收剂的催化再生
Catalytic regeneration of energy-efficient absorbent for CO2 capture
综述了近年催化剂辅助溶剂再生技术在低温节能CO2脱附中的研究进展。对几类常见的固体酸催化剂进行了讨论,并对每种催化剂的特点、缺点和目前取得的研究成果进行论述。根据最新的研究成果,研究了催化剂催化CO2脱附的促进机制以及Lewis酸、Brønsted酸2种酸活性位点的促进作用。最后,对催化溶剂再生用于燃烧后CO2捕集目前存在的问题进行了分析,为今后的研究方向提供思路。
This article reviews the latest research progress on catalyst-assisted solvent regeneration technology in low-temperature energy-saving CO2 desorption.Several types of common solid acid catalysts are expounded,and the characteristics,drawbacks and current research results achieved for each catalyst are described.According to the latest research results,the promotion mechanism of catalyst-catalyzed CO2 desorption and the promotion action of two kinds of acid active sites,Lewis acid and Brønsted acid,are studied.Finally,the current problems existed in catalytic solvent regeneration for post-combustion CO2 capture are analyzed to provide ideas for research direction in the future.
