摘　　要：使用液体吸收剂来捕获CO_(2)已经应用于工业化进程中。根据亨利定律,吸收和再生过程应分别在低温和高温下进行,这需要较高的能耗。作为一种解决方案,将纳米颗粒添加到吸收剂中,可以达到减少吸收和再生过程中所需能量的目的。本文综述了纳米颗粒强化的醇胺吸收剂在提高吸收剂反应动力学和降低吸收剂再生能耗方面的研究现状,基于传统醇胺CO_(2)吸收剂,从机理和现象两个方面对纳米颗粒强化的吸收剂的研究进展和发展趋势进行了分析,为CO_(2)吸收剂的筛选与利用提供相应的评估、论证和建议。The use of liquid absorbents to capture CO_(2)has been actually used in the process of industrialization.According to Henry’s law,the absorption and regeneration processes must be performed at low and high temperatures,respectively,which requires more energy consumption.As a solution,adding nanoparticles to the absorbent can achieve the goal of reducing the energy required for the absorption and regeneration process.This article reviews the current research status of nanoparticle-enhanced alcohol amine absorbents in improving the reaction kinetics of the absorbent and reducing the energy consumption of the absorbent regeneration.Based on the traditional alcohol amine CO_(2)absorbent,the nanoparticle-enhanced properties are enhanced from two aspects:mechanism and phenomenon.The research progress and development trend of absorbents are analyzed,and corresponding evaluations,demonstrations and suggestions are provided for the selection and utilization of CO_(2)absorbents.
