Titre : Ce0.8Sm0.2O2−δ−La0.8Sr0.2MnO3−δ dual-phase omposite hollow fiber membrane for oxygen separation Type de document : texte imprimé Auteurs : Wei Li, Auteur ; Ting-Fang Tian, Auteur ; Feng-Yuan Shi, Auteur Année de publication : 2009 Article en page(s) : pp. 5789–5793 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Dense ceramic oxygen separation membrane Cryogenic distillation process Résumé : The dense ceramic oxygen separation membrane holds promise to reduce the oxygen production cost significantly over the current mature cryogenic distillation process. Preparation of membranes in hollow fiber geometry is expected to lead to a remarkable increase in the oxygen production capacity of the membrane unit. Gas-tight Ce0.8Sm0.2O2−δ−La0.8Sr0.2MnO3−δ dual-phase composite hollow fibers were prepared by a phase-inversion/sintering technique. A stable oxygen permeation rate of 3.2 × 10−7 mol·cm−2·s−1 was measured under air/He gradient at 950 °C, and 3.0 × 10−7 mol·cm−2·s−1 was found under air/CO2 gradient. It was also found that oxygen permeation through the hollow fiber can be well-described by the Wagner equation and assuming that the gas flow in the core of the fiber conforms to the plug flow model.
