Title
(EN) PROCESSES FOR THE PRODUCTION OF TETRAHYDROFURAN, GAMMA-BUTYROLACTONE AND/OR BUTANEDIOL FROM SALTS OF SUCCINIC ACID
(FR) PROCÉDÉS DE PRODUCTION DE TÉTRAHYDROFURANE, DE GAMMA-BUTYROLACTONE ET/OU DE BUTANEDIOL À PARTIR DE SELS D'ACIDE SUCCINIQUE
Abstract
(EN) A process for making a hydrogenated product includes providing a clarified DAS- containing fermentation broth; distilling the broth under super atmospheric pressure at a temperature of >100°C to about 300°C to form an overhead that includes water and ammonia, and a liquid bottoms that includes SA, and at least about 20 wt% water; cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a liquid portion in contact with a solid portion that is substantially pure SA; separating the solid portion from the liquid portion; recovering the solid portion; hydrogenating the solid portion in the presence of at least one hydrogenation catalyst to produce the hydrogenated product including at least one of THF, GBL or BDO; and recovering the hydrogenated product.
(FR) L'invention concerne un procédé de production d'un produit hydrogéné. Ce procédé consiste : à obtenir un bouillon de fermentation contenant du DAS clarifié; à distiller le bouillon à une pression supra-atmosphérique et à une température de >100°C à environ 300°C pour obtenir un distillat de tête contenant de l'eau et de l'ammoniac, un résidu liquide contenant de l'acide succinique et au moins environ 20% en poids d'eau; à refroidir le résidu jusqu'à une température suffisante pour entraîner la séparation du résidu en une partie liquide en contact avec une partie solide constituée d'acide succinique sensiblement pur; à séparer la partie solide de la partie liquide; à récupérer la partie solide; à hydrogéner la partie solide en présence d'au moins un catalyseur d'hydrogénation pour obtenir le produit hydrogéné contenant au moins du tétrahydrofurane (THF), de la gamma-butyrolactone (GBL) et/ou du butanediol (BDO); et à récupérer le produit hydrogéné.
