Reactor Scale-up for Fluidized Bed Conversion of Ethane to Vinyl Chloride / Daniel A. Hickman in Industrial & engineering chemistry research, Vol. 49 N° 21 (Novembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 21 (Novembre 2010) Titre : Reactor Scale-up for Fluidized Bed Conversion of Ethane to Vinyl Chloride Type de document : texte imprimé Auteurs : Daniel A. Hickman, Auteur ; Mark E. Jones, Auteur ; Zoran R. Jovanovic, Auteur Année de publication : 2011 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Fluidized  bed  Fluidization  Scale  effect  Extrapolation  Reactor Résumé : Novel LaOCl/LaCl3 catalysts have been discovered that enable the production of vinyl chloride monomer from ethane. An ethane-based process would result in both capital savings and raw materials savings when compared to the current most effective vinyl technology. These materials are unique in the world of chlorination/ oxychlorination as the mechanism for chlorination over LaOCl/LaCl3 occurs on a catalyst without a redox metal center, unlike the conventional CuCl2 catalysts used for oxychlorination, where the Cu species are reducible. This report focuses on the engineering approaches taken and the challenges encountered in the scale-up of a fluidized bed reactor based on this catalyst technology. The objective is to highlight the application of chemical reaction engineering principles to an industrial reactor scale-up, with special attention to the unexpected and atypical challenges encountered in this development effort.
