Research progress on chemical absorption method for capturing carbon dioxide
In recent years,due to the massive burning of fossil fuels,CO2 emissions have increased dramatically,which has caused a series of ecological problems.Therefore,it is urgent to study more effective carbon dioxide capture technologies and more efficient carbon dioxide absorbents.After considering the three carbon dioxide capture process technologies of pre-combustion capture,post-combustion capture and oxygen-enriched combustion,scholars find that the post-combustion cap-ture process technology is the most suitable for industrial applications.As an efficient,energy-saving and relatively mature emerging technology for CO2 capture after combustion,chemical absorption is one of the most widely used and potential cap-ture technologies in power plants.Firstly,the research status of carbon capture technology was introduced,and then four kinds of chemical absorbents that were paid close attention to in the current carbon capture technology were emphatically described,including organic amine solution absorbents,ionic liquid absorbents,ammonia aqueous solution absorbents and new phase change absorbents.The capture principle,research status,advantages and disadvantages of these four absorbents,and the direction of improvement were discussed separately.
