Computational fluid dynamics simulation of fluid catalytic cracking in a rotating fluidized bed in a static geometry / Waldo Rosales Trujillo in Industrial & engineering chemistry research, Vol. 49 N° 11 (Juin 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 11 (Juin 2010) . - pp. 5288–5298 Titre : Computational fluid dynamics simulation of fluid catalytic cracking in a rotating fluidized bed in a static geometry Type de document : texte imprimé Auteurs : Waldo Rosales Trujillo, Auteur ; Juray De Wilde, Auteur Année de publication : 2010 Article en page(s) : pp. 5288–5298 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Fluid  Dynamics Résumé : The application of a rotating fluidized bed in a static geometry to fluid catalytic cracking is evaluated by means of computational fluid dynamics (CFD) simulations using an Eulerian−Eulerian model and the kinetic theory of granular flow. The reactions are described by a 10-lump model. First, the reaction kinetics is based on currently allowable cracking temperature and catalyst activity. Typical reactor dimensions required are presented, and an evaluation of the process intensification potential is made, based on a comparison with riser technology. Next, the possibility of using a higher cracking temperature or a more active catalyst is evaluated.
