| Abstract: | The present invention relates to a sorbent material for separation, preferably isothermal separation, of carbon dioxide from a gas mixture. Said sorbent material comprises either a cross-linked and substituted branched polyethylenimine containing a substituent –CH2–R substituting an amine nitrogen and a linker moiety –L– connecting amine nitrogens, or a solid support impregnated with or coated with a substituted branched polyethylenimine containing a substituent –CH2–R substituting an amine nitrogen. The present invention further provides processes of manufacturing the sorbent materials and methods of separation of carbon dioxide from a gas mixture using said sorbent materials. |
