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.
