Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 5 (Mars 2010) . - pp. 2326–2335 Titre : Dynamic simulation of sorption enhanced reaction processes for biodiesel production Type de document : texte imprimé Auteurs : Ankur Kapil, Auteur ; Shrikant A. Bhat, Auteur ; Jhuma Sadhukhan, Auteur Année de publication : 2010 Article en page(s) : pp. 2326–2335 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Dynamic  simulation;  Biodiesel;  Sorption  enhanced  reactors;  Fatty  acid  methyl  ester;  Simulated  moving  bed  reactors Résumé : The objective of this work was to establish fixed bed sorption enhanced reactors (SER) and simulated moving bed reactors (SMBR) for the production of high purity biodiesel (fatty acid methyl ester, FAME) using esterification reactions between fatty acids (FA) in used oils and methanol. This study has demonstrated that these processes have tremendous potential in terms of overcoming the low conversion and separation difficulties that are faced in conventional biodiesel production processes. Additionally, the SMBR process operating conditions can be optimized to produce FAME at a desired purity in a continuous mode. The novelty of this work lays in the development of generic and comprehensive dynamic simulation and systematic parametric analysis frameworks. These were used to deduce the following operating conditions for achieving more than 90% conversion of FA and 80% purity of FAME, from an SMBR process: switching time of 900 s, length of 0.25 m, and feed, raffinate, and eluent flow rate ratios of 0.41, 0.49, and 0.75, for a given velocity of 2.4 × 10−4 m/s in the reaction zone.
