Abstract (en)

[origin: FR2909010A1] Medium for extraction of carbon dioxide from a gaseous effluent, comprises a product of acid base reaction between a base (mixture) (I) of amidine or guanidine and a hydroxyl/thiol compound (mixture) (II). Medium for extraction of carbon dioxide from a gaseous effluent, comprises a product of acid base reaction between a base (mixture) (I) of amidine or guanidine compound of formula R 2R 3N-C(R 4)=NR 1 and a hydroxyl/thiol compound (mixture) (II) of formula R(ZH) n. R 1-R 3, R 5, R 6alicyclic, heterocyclic, (mono or poly)aromatic hydrocarbon (all optionally substituted), aliphatic hydrocarbon or H; R 4alicyclic, heterocyclic, (mono or poly)aromatic hydrocarbon (all optionally substituted), aliphatic hydrocarbon, H or -NR 5R 6; R : mono or multivalent aliphatic, alicyclic or optionally substituted heterocyclic or (mono or poly)aromatic; Z : O and/or S; and n : 1-20, preferably 1-6. An independent claim is included for capturing carbon dioxide, comprising contacting gas effluent to be treated containing carbon dioxide with the extraction medium, to impoverish the effluent gas of carbon dioxide and to enrich the extraction medium in carbon dioxide and a regenerating the extraction medium and generating carbon dioxide rich gas.
