A. Uguina, Auteur ; Sotelo, J. L., Auteur ; J. A. Delgado, Auteur Année de publication : 2009 Article en page(s) : pp. 7301–7307 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Liquid-phase adsorption C13 Isomers Fixed bed H-ZSM-5 (Si/Al = 200) Breakthrough curves Résumé : Multicomponent liquid-phase adsorption of C13 paraffins (mainly monomethyldodecanes and tridecane) onto a fixed bed of H-ZSM-5 (Si/Al = 200) has been studied (428 K and 21 barg), obtaining complete breakthrough curves for all the solutes, in order to ensure that equilibrium between the liquid feed and the adsorbent was achieved. The concentration of adsorbates in the feed mixture has been varied by diluting a concentrated mixture of C13 paraffins with a nonadsorbing solvent (2,2,4-trimethylpentane) in different proportions. The relationship between the branching position of the isomer and its adsorption affinity has been studied. The following affinity order is obtained (estimated as adsorbed concentration/liquid concentration): 2-MC12 ≈ 3-MC12 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie900419k [article] Adsorption behavior of a mixture of C13 isomers onto a fixed-bed of H-ZSM-5 [texte imprimé] / M.
