摘要
化学法吸收是中低浓度含CO_(2)尾气规模化捕集的主流技术路线,CO_(2)热解吸是化学吸收剂的常规解吸方法,但存在能耗高、解吸速率慢、降解损失等缺陷。为了克服这些缺点,研究人员对CO_(2)吸收剂解吸进行了多种路线的研究,对CO_(2)吸收剂的新型解吸技术进展进行综述,包括电驱动解吸、催化解吸、超重力解吸、微波解吸、降膜解吸,分析了各技术促进CO_(2)解吸的基本原理、优缺点及相对于现有技术的提升效果,并对CO_(2)吸收剂新型解吸技术的发展进行了展望。
Chemical absorption method represents the mainstream technological route for large-scale capture of low-medium concentration CO_(2)-containing exhaust gas.Thermal desorption of CO_(2)from absorbents is a conventional method for regenerating chemical absorbents.However,it suffers from drawbacks such as high energy consumption,low desorption rate,and degradation loss.To overcome these drawbacks,researchers have explored various routes for desorption of CO_(2)absorbents.This review summarizes the progress in novel desorption technologies for CO_(2)absorbents,including electrically-driven desorption,catalytic desorption,supergravity desorption,microwave desorption,and falling-film desorption.The fundamental principles,advantages,and disadvantages of these novel desorption technologies are analyzed,and the improvements achieved by them relative to the existing technologies are summarized.Furthermore,the development prospects of novel desorption technologies for CO_(2)absorbents are given.
