Combustion of reactive solutions impregnated into a cellulose carrier / E.M. Lennon in Chemical engineering journal, Vol. 174 N° 1 (Octobre 2011) 

Public ISBD [article]  in Chemical engineering journal > Vol. 174 N° 1 (Octobre 2011) . - pp.333–340 Titre : Combustion of reactive solutions impregnated into a cellulose carrier : Modeling of two combustion fronts Type de document : texte imprimé Auteurs : E.M. Lennon, Auteur ; M.C. Tanzy, Auteur ; V.A. Volpert, Auteur Année de publication : 2012 Article en page(s) : pp.333–340 Note générale : Génie chimique Langues : Anglais (eng) Mots-clés : Combustion  synthesis  Combustion  modeling  Nanomaterial  synthesis  Reaction  fronts Résumé : We develop and solve a novel model for the combustion of reactive solutions impregnated into a cellulose carrier. This procedure has been shown to be effective in the synthesis of metallic oxides with a nanoscale microstructure, which are suitable for catalyst applications. The model involves three reactions, (i) combustion of the carrier matrix, (ii) an endothermic reaction related to the decomposition or gasification of the synthesis reaction precursors and (iii) the exothermic oxide synthesis reaction. This model is shown to provide qualitative agreement with experimental observations. A parametric study of the model demonstrates that increasing the heat released via the leading cellulose burning reaction (i) is most favorable in terms of increasing the reaction yield and providing conditions for smaller size of the synthesized material.
