Preparation of robust, thin zeolite membrane sheet for molecular separation / Wei Liu in Industrial & engineering chemistry research, Vol. 50 N° 20 (Octobre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 20 (Octobre 2011) . - pp. 11677-11689 Titre : Preparation of robust, thin zeolite membrane sheet for molecular separation Type de document : texte imprimé Auteurs : Wei Liu, Auteur ; Jian Zhang, Auteur ; Nathan Canfield, Auteur Année de publication : 2011 Article en page(s) : pp. 11677-11689 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Zeolite  Inorganic  membrane  Preparation Résumé : This paper reports a feasibility study on the preparation of zeolite membrane films on a thin, porous metal support sheet (50 μm thick). Zeolite sodium A (NaA) and silicalite zeolite frameworks are chosen to represent syntheses of respective hydrophilic-type and hydrophobic-type zeolite membranes on this new support. It is found that a dense, continuous intergrown zeolite crystal layer at a thickness less than 3 μm can be directly deposited on such a support by using direct and secondary growth techniques. The resulting membrane shows excellent adhesion on the metal sheet. Molecular-sieving functions of the prepared membranes are characterized with ethanol/water separation, CO2 separation, and air dehumidification. The results show great potential to make flexible metal-foil-like zeolite membranes for a range of energy conversion and environmental applications.
