摘要

化学吸收法是目前最具规模化应用的CO

捕集技术之一，但胺吸收剂在捕集过程中易降解，导致捕集成本增加。相比于传统单乙醇胺（MEA），N-（2-羟乙基）乙二胺（AEEA）具有CO

吸收量高和反应速率快等优点。然而AEEA在含氧环境下易降解的问题限制了其进一步应用。针对AEEA开展了负载CO

、高温和高O

分压条件下的降解实验研究，开发了采用β-环糊精（β-CD）作为载体包合带有活性羟基的酚类作为AEEA体系的降解抑制剂，分析添加降解抑制剂前后AEEA的性能变化，提出了“物理包合-化学协同-自由基还原”抑制氧化降解的协同方法。研究发现，随降解时间的延长，空白AEEA的CO

吸收/解吸性能和降解率呈阶梯式下降趋势。而添加0.1 vt% β-CD包合物后，CO

吸收量提高131.03%，解吸量提高58.49%。

Abstract

Chemical absorption is one of the most

scalable CO

capture technologies currently available

yet amine absorbents are prone to degradation during the capture process

leading to increased costs. Compared with conventional monoethanolamine (MEA)

N-(2-hydroxyethyl)ethylenediamine (AEEA) offers advantages such as higher CO

absorption capacity and faster reaction rate. However

its susceptibility to degradation in oxygen-containing environments limits further application. To address this

degradation experiments were conducted on AEEA under CO

loaded

high temperature

and high O

partial pressure conditions. A degradation inhibitor was developed using β-cyclodextrin (β-CD) as a carrier to encapsulate phenols containing active hydroxyl groups for the AEEA system. Performance changes of AEEA before and after adding the inhibitor were analyzed

and a synergistic approach termed "physical encapsulation–chemical synergy–free radical reduction" was proposed to suppress oxidative degradation. The results showed that with prolonged degradation time

the CO

absorption/desorption performance and degradation rate of blank AEEA declined in a stepwise manner. In contrast

after adding 0.1 vt% of the β-CD inclusion complex

the CO

absorption capacity increased by 131.03%

and the desorption capacity increased by 58.49%.
