摘要： Disclosed herein is a method for improving the total energy demand required to separate carbon dioxide (CO2) from an aqueous ionic absorbent solution in a post-combustion carbon capture process. The method involves (a) contacting a flue gas stream containing CO2 with an aqueous ionic absorbent solution under absorption conditions to absorb at least a portion of the CO2 from the flue gas stream and form a CO2-aqueous ionic absorbent solution stream, wherein the aqueous ionic absorbent solution comprises one or more diluents and an ionic absorbent containing a cation and an anion comprising an amine moiety; and (b) subjecting at least a portion of the CO2-aqueous ionic absorbent solution stream to desorption conditions to form a CO2-rich stream and an aqueous ionic absorbent solution stream having a reduced CO2 content.
