Abstract

Le solvant comporte un agent chélateur métallique et un agent gonflant caustique, le solvant étant préparé sous forme aqueuse ou sous forme solide. On met le solvant en contact avec des matières cellulosiques pour en faire précipiter la cellulose. On peut alors hydrolyser la cellulose récupérée à l'aide d'une enzyme de cellulose ou d'un acide pour obtenir du glucose, la lignine étant éliminée avant ou après hydrolyse. Utilisation des déchets de cellulose comme sources de remplacement de combustibles, d'aliments, de produits chimiques et d'autres produits utiles.
