Poly (allylamine) – mesoporous silica composite materials for CO2 capture from simulated flue gas or ambient air / Watcharop Chaikittisilp in Industrial & engineering chemistry research, Vol. 50 N° 24 (Décembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 24 (Décembre 2011) . - pp. 14203–14210 Titre : Poly (allylamine) – mesoporous silica composite materials for CO2 capture from simulated flue gas or ambient air Type de document : texte imprimé Auteurs : Watcharop Chaikittisilp, Auteur ; Ratayakorn Khunsupat, Auteur ; Thomas T. Chen, Auteur Année de publication : 2012 Article en page(s) : pp. 14203–14210 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Mesoporous  silica  Composite  materials Résumé : Low-molecular-weight poly(allylamine) is prepared via free-radical polymerization, and the resulting polymer is impregnated into mesocellular silica foams at different amine loadings. The resulting poly(allylamine)–silica composites are demonstrated as effective adsorbents for the extraction of carbon dioxide from dilute (simulated flue gas) and ultradilute (simulated ambient air) gas streams. The composite adsorbents are shown to have comparable adsorption capacities to more-conventional poly(ethyleneimine)–silica adsorbents. Potential advantages of poly(allylamine)-derived adsorbents are discussed.
