Novel in situ batch reactor with a facile catalyst separation device for biodiesel production / Yanjun Jiang in Industrial & engineering chemistry research, Vol. 51 N° 46 (Novembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 46 (Novembre 2012) . - pp. 14935-14940 Titre : Novel in situ batch reactor with a facile catalyst separation device for biodiesel production Type de document : texte imprimé Auteurs : Yanjun Jiang, Auteur ; Hanqi Gu, Auteur ; Liya Zhou, Auteur Année de publication : 2013 Article en page(s) : pp. 14935-14940 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Production  Catalyst  Reactor  Batchwise  In  situ Résumé : In an effort to reduce the production cost of biodiesel and realize the lipase recovery of the in situ transesterification technology, a reactor with facile catalyst separation device was developed in this study. Compared with conventional method of biodiesel production, this improved reactive extraction technology can realize not only the biodiesel synthesis in a single step, but also the separation of immobilized lipases from the oilseed residues easily. This technology may present a sustainable, economically attractive process for biodiesel production. J. curcas L. seed, methanol, Lipozyme TL IM, and cosolvent n-hexane were used in this study. The effect of various process parameters on the yield of fatty acid methyl esters (FAMEs) was investigated. The highest FAMEs yield of 90.6% could be achieved under the optimum conditions: n-hexane/seed ratio of 3.5:1 mL/g, methanol/oil molar ratio of 6:1, 15% (w/w) of Lipozyme TL IM, reaction temperature of 45 °C, water content of 1.0%, and reaction time of 12 h. The lipase could maintain more than 40% of its initial activity after 13 batches operation under optimal reaction conditions. This simple in situ transesterification technology with facile catalyst separation device can be a potential route for biodiesel production, which may greatly reduce the processing steps and costs.
