Abstract

On hydrolyse des matières premières cellulosiques à l'aide d'un acide sulfurique dilué pour éliminer l'hémicellulose, après quoi on sépare le résidu solide et on lui ajoute de l'acide sulfurique concentré pour dissoudre la cellulose contenue dans le résidu solide. Après mélange du résidu avec l'acide sulfurique concentré dansé des conditions de réaction soigneusement contrôlées, on fait reprécipiter la cellulose en ajoutant de l'eau ou un solvant organique tel que le méthanol. On peut alors hydrolyser la cellulose récupérée à l'aide d'une enzyme de cellulose et/ou d'un acide dilué pour obtenir un rendement élevé de glucose. On récupère une proportion importante de l'acide sulfurique, que l'on reconcentre. Utilisation des déchets cellulosiques comme sources de remplacement de combustibles, d'aliments, de produits chimiques et d'autres produits utiles.Cellulosic raw materials are hydrolyzed with dilute sulfuric acid to remove hemicellulose, after which the solid residue is separated and concentrated sulfuric acid is added to it to dissolve the cellulose contained in the solid residue. After mixing the residue with concentrated sulfuric acid under carefully controlled reaction conditions, the cellulose is reprecipitated by adding water or an organic solvent such as methanol. The recovered cellulose can then be hydrolyzed using a cellulose enzyme and / or a dilute acid to obtain a high yield of glucose. A significant proportion of the sulfuric acid is recovered, which is reconcentrated. Use of cellulosic waste as an alternative source of fuel, food, chemicals and other useful products.
