CO2捕集及分离方法研究现状与进展

Research Status and Progress of CO2 Capture and Separation Methods

捕获及有效分离二氧化碳,不仅可以实现碳减排,而且可以有效控制二氧化碳排放引起的温室效应。本文重点综述了吸收法、膜分离法、低温分离法和吸附法四种CO2捕集及分离方法。通过比较发现,吸附法由于具有可操作性强、成本低、可再生效率高等优点,是未来CO2捕集及分离的主要方法。

Carbon dioxide capture and effective separation can not only achieve carbon emission reduction,but also effectively control the greenhouse effect caused by carbon dioxide emissions.This paper focuses on the four methods of CO2 capture and separation:absorption,membrane separation,low temperature separation and adsorption method.Through comparison,it is found that the adsorption method is the main method for CO2 capture and separation in the future due to its advantages of strong operability,low cost,and high renewable efficiency.
