Public ISBD [article]  in Chemical engineering journal > Vol. 156 N° 1 (Janvier 2010) . - pp. 157-164 Titre : Mathematical model : retention of beryllium on flow-through fixed bed reactor of Amb-IR-120 Type de document : texte imprimé Auteurs : Sameh H. Othman, Auteur ; Mahmoud M. Saleh, Auteur ; M. Demerdash, Auteur Année de publication : 2010 Article en page(s) : pp. 157-164 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Adsorption  Modeling  Amb-IR-120  Fixed-bed Index. décimale : 660 Résumé : A mathematical model was proposed to simulate the beryllium uptake within a fixed porous flow-through reactor. The effects of various structural, kinetic and hydraulic parameters on the behavior of the flow reactor were studied. These include linear velocity of the fluid, packing density, void fraction and adsorption coefficient. The proposed mathematical model is solved analytically and its predictions were compared with experimental results. A reasonable agreement between model predictions and experimental data was obtained. The model is approved to simulate the behavior of beryllium uptake along the fixed bed reactor of Amb-IR-120 and can be easily applied to similar systems.
