烟气CO_(2)捕集分离技术研究进展

Research Progress on CO_(2) Capture and Separation Technology from Flue Gas

燃烧后烟气CO_(2)捕集分离是目前最成熟的CO_(2)捕集方法,然而传统的吸收、吸附等过程往往存在捕集效率不高、CO_(2)容量小、再生能耗大等问题,因此获得高效、稳定、低能耗的CO_(2)捕集材料成为当前研究的重点。本文对烟气CO_(2)捕集分离法中的溶剂吸收法、膜分离法和固相吸附法进行了较为全面的分析,重点阐述了吸收剂、膜材料和吸附剂的研究进展,这可为相关研究提供一些有益的借鉴。

CO_(2) capture and separation of post-combustion flue gas is currently the most mature CO_(2) capture method.However,traditional absorption or adsorption processes have some shortcomings,such as low capture efficiency,small CO_(2) capacity,and high energy consumption for regeneration.Therefore,obtaining CO_(2) capture materials of high efficiency,stability,and lowenergy consumption has become the focus of current research about CO_(2) capture and separation.The solvent absorption,membrane separation and solid phase adsorption in CO_(2) capture and separation method from flue gas were comprehensively analyzed,and the research progress on absorbent,membrane material and adsorbent were emphatically expounded.Some helpful reference were provided for related research.
