摘　　要：碳捕集、利用与封存(CCUS)技术是缓解全球气候变化的重要措施之一。纳米颗粒因具有良好表面效应和体积效应,能够强化CO2捕集传质性能而备受青睐,其可增大胺法吸收CO2过程中的传质系数并减少溶剂再生所需的能量,有望进一步提高CO2捕集效率、降低能耗。本文从纳米颗粒强化胺法吸收CO2过程出发,讨论了纳米颗粒强化吸收的3种机理(抑制气泡聚并机理、传输机理、边界层混合机理),总结了近年来国内外最新研究进展,论述了纳米颗粒强化CO2吸收过程中的主要影响因素,指出纳米颗粒对CO2吸收过程的强化是多重因素共同作用的结果,并对该技术的未来研究方向作了展望。The technology of carbon capture,utilization and storage(CCUS)is one of the important measures to alleviate global climate change.Nanoparticles with good surface and volume effect are favored because of their ability to enhance the mass transfer performance of CO2 capture.They can increase the mass transfer coefficient of CO2 absorption in amine solutions and reduce the energy needed for solvent regeneration,which is expected to further improve the CO2 capture efficiency and reduce energy consumption.In this paper,three mechanisms of nanoparticles enhanced CO2 absorption are discussed:the mechanism for inhibition of bubble coalescence,the mechanism for shuttle effect and the mechanism for mixing of the gas-liquid boundary layer.The latest research progress at home and abroad in recent years is summarized,and the main influencing factors in the process of CO2 absorption enhanced by nanoparticles are discussed.It points out that the enhancement of CO2 absorption process by nanoparticles is the result of the joint action of multiple factors.Moreover,the future direction of this technology is prospected.
