The disclosure includes a method, process and apparatus for the conversion of biomass to carboxylic acids and/or primary alcohols. The system may include a pretreatment/fermentation subsystem operate e to produce a fermentation broth containing carboxylic acid salts from biomass, such as lignocellulosic biomass. The system may also include a dewatering subsystem >@5r0ble to remove excess water from the fermentation broth to produce a concentrated product. The system may also includes an acid springing subsystem operable to produce a mixed carboxylic acid product. The system may also include a hydrogenation subsystem operable to produce an alcohol mixture, such as a mixture containing primary alcohols. Methods of operating this system or other systems to obtain a carboxylic acid or alcohol mixture are also provided.
L'invention concerne un procédé, un processus et un appareil destinés à la conversion de biomasse en acides carboxyliques et/ou en alcools primaires. Ce système peut comporter un sous-système de pré-traitement/fermentation qui fonctionne de manière à produire un bouillon de fermentation contenant des sels d'acide carboxylique provenant de la biomasse, telle qu'une biomasse lignocellulosique. Ce système peut aussi comporter un sous-système de déshydratation conçu pour éliminer l'excès d'eau provenant du bouillon de fermentation afin d'engendrer un produit concentré. Ledit système peut aussi englober un sous-système de mélange d'acides élaboré pour générer un produit d'acide carboxylique mélangé et un sous-système d'hydrogénation destiné à produire un mélange d'alcools, tel qu'un mélange contenant des alcools primaires. Cette invention concerne aussi des procédés de fonctionnement de ce système ou d'autres systèmes permettant d'obtenir un acide carboxylique ou un mélange d'alcools.
