Abstract

Det er tilveiebrakt en høy-effektivitet, lav-energitype, blandet absorbent for separasjon av karbondioksid, som har en rask reaksjonshastighet med karbondioksid og en høy karbondioksidabsorpsjonskapasitet og som ikke krever en stor energimengde for regenerering av absorbenten, i forbindelse med lav risiko for absorbentoksidasjon. Absorbenten innbefatter en blandet, vandig løsning av: 100 vektdeler av en forbindelse ifølge Formel 1 som har én alkoholisk hydroksylgruppe og ett primæramin i molekylstrukturen med ingen substituent på alfakarbonet tilstøtende aminet og begge av en alkylsubstituent og en alkoholisk hydroksylgruppe på betakarbonet, og 1-60 vektdeler av en heterosyklisk forbindelse ifølge Formel 2 som har minst ett amin i ringen: Formel 1 Formel 2 hvor R1, R2, R3, R4, R5 og X er som definert i beskrivelsen.A high-efficiency, low-energy, mixed absorbent is provided for carbon dioxide separation, which has a fast reaction rate with carbon dioxide and a high carbon dioxide absorption capacity, and which does not require a high amount of energy to absorb the absorbent, in connection with low risk of absorbent oxidation. The absorbent includes a mixed aqueous solution of: 100 parts by weight of a compound of Formula 1 having one alcoholic hydroxyl group and one primary amine in the molecular structure with no substituent on the alpha carbon adjacent to the amine and both of an alkyl substituent and an alcoholic hydroxyl group on the beta carbon, and 1-60 parts by weight of a heterocyclic compound of Formula 2 having at least one amine in the ring: Formula 1 Formula 2 wherein R1, R2, R3, R4, R5 and X are as defined in the specification.
