Low-pressure packed-bed gas-phase dehydration of glycerol to acrolein / Yan, Wei in Industrial & engineering chemistry research, Vol. 48 N° 7 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 7 (Avril 2009) . - pp. 3279–3283 Titre : Low-pressure packed-bed gas-phase dehydration of glycerol to acrolein Type de document : texte imprimé Auteurs : Yan, Wei, Auteur ; Galen J. Suppes, Auteur Année de publication : 2009 Article en page(s) : pp. 3279–3283 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Glycerol  Gas-phase  dehydration  Solid  acid  catalysts Résumé : Glycerol has become readily available from biodiesel industry. High functionality and relatively low price make it a potential building block to produce value-added derivatives such as acrolein. In this study, low-pressure packed-bed gas-phase dehydration of glycerol was investigated in presence of various solid acid catalysts, including H3PO4/activated carbon catalyst. Dehydration mechanism over H3PO4/activated carbon catalyst was validated. In the presence of H3PO4/activated carbon catalyst, yield of acroelin (66.8%) and selectivity to acrolein (84.0%) were achieved at the temperature of 260 °C and the pressure of 0.85 bar.
