Methodology of non-equilibrium thermodynamics for kinetics research of CO ₂ capture by ionic liquids

In this paper, the methodology of non-equilibrium thermodynamics is introduced for kinetics research of CO ₂ capture by ionic liquids, and the following three key scientific problems are proposed to apply the methodology in kinetics research of CO ₂ capture by ionic liquids: reliable thermodynamic models, interfacial transport rate description and accurate experimental flux. The obtaining of accurate experimental flux requires reliable experimental kinetics data and the effective transport area in the CO ₂ capture process by ionic liquids. Research advances in the three key scientific problems are reviewed systematically and further work is analyzed. Finally, perspectives of non-equilibrium thermodynamic research of the kinetics of CO ₂ capture by ionic liquids are proposed.
