Titre : Pt-Sn/MgAl2O4 as n-butane dehydrogenation catalyst in a two-zone fluidized-bed reactor Type de document : texte imprimé Auteurs : M. P. Lobera, Auteur ; C. Téllez, Auteur ; J. Herguido, Auteur Année de publication : 2009 Article en page(s) : pp. 6573–6578 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : n-Butane dehydrogenation Pt-Sn/MgAl2O4 catalyst Two-zone fluidized-bed reactor Résumé : n-Butane dehydrogenation over a Pt-Sn/MgAl2O4 catalyst has been carried out in a two-zone fluidized-bed reactor (TZFBR), where oxidation and reduction of this catalyst occurs in the same vessel but in separate zones. This allows working in a continuous mode with in situ catalyst regeneration, unlike traditional systems that require two different reactors or a single reactor with periodic operation. The effect of the main TZFBR operating variables was studied and its performance compared with that of a conventional fluidized-bed reactor loaded with the same catalyst and with other reactor + catalyst systems. Compared with a previous work in a similar reactor with another catalyst, the selectivity is improved because of the lower tendency to coke formation of the Pt-Sn/MgAl2O4 catalyst.
