Miscanthus sinensis fractionation by different reagents / L. Serrano in Chemical engineering journal, Vol. 156 N° 1 (Janvier 2010) 

Public ISBD [article]  in Chemical engineering journal > Vol. 156 N° 1 (Janvier 2010) . - pp. 49-55 Titre : Miscanthus sinensis fractionation by different reagents Type de document : texte imprimé Auteurs : L. Serrano, Auteur ; I. Egues, Auteur ; M. González Alriols, Auteur Année de publication : 2010 Article en page(s) : pp. 49-55 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Miscanthus  sinensis  Soda  Organosolv  Cellulose  Lignin Index. décimale : 660 Résumé : Miscanthus sinensis L. was fractionated by different reagents (ethanol, soda and soda–ethanol) in order to obtain cellulose, hemicelluloses and lignin. Characterization of original M. sinensis fibres (66.6% holocellulose, 36.1% α-cellulose, and 15.5% lignin) was done and compared with other biomass species chemical composition (alternative raw materials, agriculture residues, coniferous and leafy plants). Obtained solid fractions were chemically characterized and compared with solid fractions from other biomass products (palm oil empty fruit bunches (EFB) and rice straw) generated by similar fractionation processes (soda and organosolv). Soda process produced the solid fraction with the highest content in α-cellulose and lowest content in lignin revealing a strong fractionation effect. On the contrary, soda–ethanol process was found to present low fractionation capability. Obtained cellulose samples were characterized by FTIR to complete the chemical structure analysis. Lignin samples isolated from the liquid fractions were submitted to FTIR, 1H NMR, GPC, DSC and TGA in order to suggest suitable applications for the products based on their properties.
