Research Progress on Membrane-Based CO2 Capture Technology
CO2capture technology is one of the important technical measures to achieve carbon peaking and neutrality goals.So far,there are many technologies for CO2 capture,among which membrane separation has a wide application prospect due to its advantages such as small occupied area,low cost,simple operation and environmental protection,so it has attracted the extensive attention from many researchers.In this paper,the types and structural characteristics of high-performance CO2membrane separation materials were summarized,and the corresponding CO2 transfer mechanism and current main application research directions of the three types of membrane materials were introduced in detail.Secondly,the physicochemical characteristics of two kinds of CO2 separation membrane technologies were summarized,and the application fields of hollow-fiber membrane technology and plate membrane technology were summarized in detail.Finally,the current problems of the membrane technology and the future research direction to improve the CO2 capture capacity of the membrane-based technology are prospected.
