摘　　要：详细介绍了国内外捕集二氧化碳的方法及发展情况,重点分析了低温分离、膜分离/吸收、吸收、吸附分离和水合物法、吸收-水合/吸附耦合分离法分离捕集二氧化碳的优势及缺点。得出可以将2种或多种分离方法联合使用,避免单一使用时带来的劣势,实现高效率低能耗分离捕集CO_2气体。指出未来还需克服多种方法联合使用时对分离设备的高要求及材料稳定性等问题。In this work, the existing CO2 separation methods, such as cryogenic distillation, membrane separation or membrane absorption, conventional absorption, adsorption, gas hydrate technique, and absorption-hydration/adsorption hybrid method, are reviewed and analyzed. Based on the analysis of their advantages and disadvantages, it can come to a conclusion that the combination of more than one method has a bright prospect due to avoiding the disadvantages of separate method, which can achieve the separation with high efficiency and low energy consumption. Furthermore, the research interests in the future are proposed to solve the problems about high requirement for equipments and material stability in the combined or hybrid methods.
