Application of sulfonated carbon - based catalyst for reactive extraction of 1,3-propanediol from model fermentation mixture / Panatpong Boonoun in Industrial & engineering chemistry research, Vol. 49 N° 24 (Décembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 24 (Décembre 2010) . - pp. 12352-12357 Titre : Application of sulfonated carbon - based catalyst for reactive extraction of 1,3-propanediol from model fermentation mixture Type de document : texte imprimé Auteurs : Panatpong Boonoun, Auteur ; Navadol Laosiripojana, Auteur ; Chirakarn Muangnapoh, Auteur Année de publication : 2011 Article en page(s) : pp. 12352-12357 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Fermentation  Modeling  Catalyst Résumé : This study deals with the possibility of the application of a low-cost sulfonated carbon-based catalyst for reactive extraction to separate 1,3-propanediol (1,3-PDO) from a model solution of 1,3-PDO biologically derived from glycerol. The catalyst was synthesized by incomplete carbonization of naphthalene in sulfuric acid, and was demonstrated to be active for the acetalization of 1,3-PDO with acetaldehyde in aqueous solution. The performance of the reactive extraction process by using a sulfonated carbon-based catalyst was proven to be excellent based on the percent recovery rate of 1,3-PDO. These results along with those on the catalyst reactivity demonstrate that the carbon-based catalyst can be used to replace expensive commercial catalysts currently used such as Dowex 50-WX4-200 and Amberlite IR120.

Application of sulfonated carbon - based catalyst for solvothermal conversion of cassava waste to hydroxymethylfurfural and furfural / Wachiraporn Daengprasert in Industrial & engineering chemistry research, Vol. 50 N° 13 (Juillet 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 13 (Juillet 2011) . - pp. 7903-7910 Titre : Application of sulfonated carbon - based catalyst for solvothermal conversion of cassava waste to hydroxymethylfurfural and furfural Type de document : texte imprimé Auteurs : Wachiraporn Daengprasert, Auteur ; Panatpong Boonnoun, Auteur ; Navadol Laosiripojana, Auteur Année de publication : 2011 Article en page(s) : pp. 7903-7910 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Catalyst Résumé : This study aims to investigate the production of hydroxymethylfurfural (HMF) and furfural from cassava waste using a sulfonated carbon-based catalyst and to determine the suitable conditions for the reaction. With the use of the catalyst, the appropriate reaction medium for the production of HMF and furfural was a mixture of acetone/DMSO (70/30% w/w) and water at a ratio of 10/90% w/w. The reaction temperature and time were 250°C and 1 min, respectively, and the corresponding weight ratio of the catalyst to cassava waste was 0.05:1. Furthermore, the carbon-based catalyst was found to be highly stable and thus can potentially replace the conventional homogeneous acid catalysts such as sulfuric acid for biomass conversion to liquid alkane. Particularly, the catalyst plays an important role in enhancing hydrolysis of cellulose and hemicelluloses and promoting the dehydration of xylose and glucose to form HMF and furfural.
