摘要
生物质气中CO_(2)捕集及CH4的回收利用具有巨大经济价值和环境效益,受到各领域的广泛关注.基于中空纤维膜的气-液膜接触技术以其效率高、能耗少和操作灵活等优势被认为是CO_(2)捕集领域的重大突破.本文以中空纤维膜材料为中心,回顾了近十年来无机膜、传统有机聚合膜、有机微孔聚合膜、混合基质膜和固定载体膜的研究和发展,论述了各类中空纤维膜的CO_(2)捕集性能以及当前面临的挑战.同时从膜润湿、吸收剂以及工艺条件等方面分析了影响CO_(2)分离性能的主要因素.并提出开发低成本、高CO_(2)捕集性能和高稳定性的新型中空纤维膜以及推进膜的中试和示范试点工程作为未来发展的主流方向.
CO_(2) capture and CH4 recovery from biomass gas have great economic value and environmental benefit, and they have been widely concerned in various fields. Gas-liquid membrane contactor technology based on hollow fiber membrane is considered a major breakthrough in the field of CO_(2) capture due to its high separation efficiency, low energy consumption and flexible operation. Focusing on hollow fiber membrane materials, this paper reviewed detailly about the research and development of inorganic membranes, organic polymer membranes, mixed matrix membranes, and fixed-site-carrier membranes in the past decade, and introduced the gas separation performance and current challenges of various hollow fiber membranes, respectively. At the same time, the main factors(membrane wetting, absorbent and operation conditions) affecting CO_(2) separation performance of the hollow fiber membrane contactor were analyzed. This paper proposes that future research should focus on creating new hollow fiber membranes with low-cost, high performance of CO_(2) separation, high stability and the development of the membranes with excellent performance for pilot test.
