Title (EN) A PROCESS FOR PRODUCTION OF ETHANOL FROM LIGNOCELLULOSIC MATERIAL
(FR) PROCÉDÉ DE PRODUCTION D'ÉTHANOL À PARTIR D'UN MATÉRIAU LIGNOCELLULOSIQUE
Abstract: front page image
(EN)This invention relates to a process for production of ethanol from lignocellulosic material. Lignocellulosic material treated with dicarboxylic acid, preferably with oxalic acid, separating hemicellulosic fraction to ferment pentose sugar. The lignin is dissolve in alkali, preferably with NaOH, separating cellulose fraction for further enzymatic treatment with one or more than one cellulytic enzymes capable of hydrolyzing cellulose. Enzyme hydrolyasate further subjected to fermentation in presence of ethanol producing yeast, preferably Saccharomyces cerevisiae. The fermented broth further subjected to distillation followed by dehydration to yield ethanol.
(FR)Cette invention concerne un procédé de production d'éthanol à partir d'un matériau lignocellulosique. Le matériau lignocellulosique est traité avec un acide dicarboxylique, de préférence, avec un acide oxalique, et la fraction hémicellulosique est séparée pour fermenter le sucre pentose. La lignine est dissoute dans un alcali, de préférence, avec du NaOH, et la fraction cellulosique est séparée à des fins de traitement enzymatique supplémentaire avec une ou plus d'une enzyme cellulytique capable d'hydrolyser la cellulose. L'hydrolysat enzymatique est, en outre, soumis à fermentation, en présence d'une levure productrice d'éthanol, de préférence, Saccharomyces cerevisiae. Le bouillon fermenté est ensuite soumis à distillation, puis à déshydratation pour produire l'éthanol.
