Abstract
Divulgation d'un absorbant mixte de type basse énergie et à haute efficacité pour la séparation du dioxyde de carbone. Cet absorbant réagit rapidement avec le dioxyde de carbone et a une capacité d'absorption du dioxyde de carbone élevée. Il ne requiert pas une grande quantité d'énergie pour sa régénération et exhibe un faible risque d'oxydation. Cet absorbant comprend une solution aqueuse mixte de : 100 parties en poids d'un composé de formule 1 comportant un groupe hydroxyle alcoolique et un groupe amine primaire, aucun substituant n'étant présent sur le carbone en position alpha par rapport au groupe amine et un groupe substituant alkyle et un groupe hydroxyle alcoolique étant tous deux sur le carbone en position bêta; de 1 à 60 parties en poids d'un composé hétérocyclique de formule 2 comportant au moins un groupe amine dans le noyau (voir la formule 1) voir la formule 2), dans lesquelles R1, R2, R3, R4, R5 et X sont tels que définis dans les spécifications.
