Abstract: front page image
(EN)Continuous process for conversion of lignin to useful compounds This specification discloses a process to convert lignin as found in ligno-cellulosic biomass comprising the steps of : Pretreating the ligno-cellulosic biomass feedstock with treatment water which includes steam explosion to create a pre-treated ligno- cellulosic biomass feedstock, Converting at least a portion of the glucans and xylans to chemicals other than glucose and xylose and their respective glucose and xylose oligomers and polymers to create a ligno-cellulosic biomass stillage comprising lignin, a pre-treatment BOD concentration and a pre- treatment COD concentration, Converting the lignin of the ligno-cellulosic biomass stillage to products other than lignin by exposing the ligno-cellulosic biomass stillage to hydrogen and a first catalyst to produce a liquid phase at 25 °C, Rrecovering a treated water from the liquid phase having a post-treatment BOD concentration and a post treatment COD concentration, both of which are 50% less than the pre-treatment BOD and COD concentration and, using the treated water in at least one of the steps selected from the group consisting of a waste water treatment process and any process step preceding recovering the treated water from the liquid phase, before or after converting at least some of the carbohydrates. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.
(FR)L'invention concerne un procédé continu opérationnel pour convertir de la lignine telle que trouvée dans de la biomasse ligno-cellulosique avant et après conversion d'au moins une partie des hydrates de carbone. Selon l'invention, le procédé continu génère une suspension composée de lignine, augmente la pression de la suspension composée de lignine à une valeur ultra-haute, désoxygène la lignine dans un réacteur de conversion de lignine sur un catalyseur qui n'est pas un lit fixe sans produire de produits de carbonisation. Les produits de conversion des hydrates de carbone ou de la lignine peuvent être transformés ultérieurement en intermédiaires de polyester destinés à être utilisés dans des préformes et des bouteilles en polyester.
