Evaluation of a primary amine - functionalized ion - exchange resin for CO2 capture / W. Richard Alesi in Industrial & engineering chemistry research, Vol. 51 N° 19 (Mai 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 19 (Mai 2012) . - pp. 6907-6915 Titre : Evaluation of a primary amine - functionalized ion - exchange resin for CO2 capture Type de document : texte imprimé Auteurs : W. Richard Alesi, Auteur ; John R. Kitchin, Auteur Année de publication : 2012 Article en page(s) : pp. 6907-6915 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Carbon  dioxide  Ion  exchange  resin Résumé : A primary amine-functionalized polymeric ion-exchange resin (Lewatit VP OC 1065, Lanxess) was evaluated for use in CO2 capture applications. The polymeric resin was characterized by SEM, DRIFTS-IR, N2 adsorption isotherms, and packed bed sorption measurements to determine some of the characteristic properties of the resin. Capture capacities ranging from 1.85 to 1.15 mol CO2/kg sorbent were obtained in a packed bed reactor exposed to 10 vol % CO2 in N2 at adsorption temperatures ranging from 30 to 70 °C. The capture capacity of the resin was stable over 18 adsorption/regeneration cycles. The resin was evaluated through thermogravimetric analysis to have a low moisture adsorption (1.5 mol H2O/kg sorbent). It is possible to completely regenerate the resin under 1 atm of CO2 at 200 °C.
