Research progress of solid and liquid absorbents for carbon dioxide capture
The comparative analysis is conducted on CO2 capture technologies such as solid adsorption,solvent absorption and membrane separation.Among them,solid adsorption and liquid absorption are widely used.Based on the mechanism of CO2 adsorption and separation,the main progress of solid adsorption and liquid absorption in CO2 capture technology is summarized,including the capture mechanisms,advantages and disadvantages of solid adsorbents such as molecular sieves and metal organic frameworks(MOFs),as well as liquid adsorbents such as organic amines,carbonate solutions and ionic liquids.It also looks forward to the future development direction of CO2 capture technology,in order to provide reference for the research and application of CO2 capture technology.
