Title (EN) PROCESS AND SYSTEM FOR PRODUCTION OF ORGANIC SOLVENTS
(FR) PROCÉDÉ ET SYSTÈME POUR LA PRODUCTION DE SOLVANTS ORGANIQUES
Abstract:
(EN) The present invention relates to a process for production of organic solvents, mainly butanol, using the anaerobic fermentation by butanol, acetone, and ethanol-producing bacteria, also the invention relates to a system for carrying out of the process and product obtained by the process. The claimed process comprises pretreating plant raw material, saccharifying the pretreated material with enzymes which degrade or convert the material into sugar solution, fermenting the sugar solution by butanol, acetone, ethanol producing bacteria in a fermentor, removing organic solvents and fermentation gases, recovering end product. Moreover the pretreatment comprises a coarse milling and then a fine milling, an enzyme complex is used for the saccharification, and the enzyme complex is matched to polysaccharide components of the raw material; the fermentation is carried out with predominant production of butanol by periodic pressure reduction in the fermentor and simultaneous removal of organic solvents and fermentation gases.
(FR) La présente invention concerne un procédé de production de solvants organiques, principalement de butanol, par fermentation anaérobie de bactéries produisant du butanol, de l'acétone ou de l'éthanol, ainsi qu'un système permettant de mettre en oeuvre ce procédé, et le produit obtenu. Ledit procédé consiste à prétraiter une matière première, saccharifier le matériau prétraité avec des enzymes qui dégradent ou transforment ce matériau en solution sucrée, fermenter la solution sucrée avec des bactéries produisant du butanol, de l'acétone ou de l'éthanol dans un fermenteur, retirer les solvants organiques et les gaz de fermentation, et récupérer le produit final. Le prétraitement comprend un broyage grossier puis un broyage fin, un complexe enzymatique est utilisé pour la saccharification, et ce complexe est adapté aux polysaccharides de la matière première. La fermentation est réalisée avec production prédominante de butanol par réduction périodique de la pression dans le fermenteur et élimination simultanée des solvants organiques et des gaz de fermentation.
