摘要
膜吸收法作为膜分离和化学吸收相结合的一种新型CO_(2)捕集技术,具有装置紧凑、选择性高等优点,受到广泛关注。本文对近年来CO_(2)膜吸收用膜材料的研究进行了综述。首先介绍了在CO_(2)膜吸收中常用的有机聚合物膜和无机陶瓷膜,论述了孔径、表面孔隙率等膜结构特性对膜吸收性能的影响,总结了共混法、接枝法、涂覆法等聚合物膜和陶瓷膜常用的疏水改性方法,最后提出了目前CO_(2)膜吸收研究中存在的问题,并对其未来发展进行了展望。
The membrane absorption method,as a novel CO_(2) capture technology that combines membrane separation and chemical absorption,has attracted widespread attention due to its advantages such as compact structure and high selectivity.This paper reviews the research on membrane materials for CO_(2) membrane absorption in recent years.Firstly,the commonly used organic polymer membranes and inorganic ceramic membranes in CO_(2) membrane absorption are introduced.In addition,the effects of membrane structural characteristics such as pore size and surface porosity on membrane absorption are discussed.Furthermore,the commonly used hydrophobic modification methods for polymer and ceramic membranes are summarized,such as blending,grafting,and coating methods,including blending,grafting and coating methods.Finally,the current problems in CO_(2) membrane absorption research are proposed,and its future development is prospected.
