Title (EN) DEPOLYMERIZATION OF LIGNIN FOR THE PRODUCTION OF BIO-BASED POLYOLS AND PHENOLS AND LIGNIN-BASED PF/PU/EPOXY RESINS/FOAMS
(FR) DÉPOLYMÉRISATION DE LIGNINE POUR LA PRODUCTION DE POLYOLS ET DE PHÉNOLS D'ORIGINE BIOLOGIQUE ET DE RÉSINES/MOUSSES DE PF/PU/ÉPOXY À BASE DE LIGNINE
Abstract:
(EN) The present relates to a process for the depolymerization of a feedstock comprising lignin producing depolymerized lignins comprising the loading of the feedstock, a catalyst, a polyalcohol, and water into a reactor; heating the reactor to about 150-300°C to depolymerize the lignin producing a depolymerized lignin mixture; stopping the depolymerization reaction by quenching with cold water; acidifying/neutralizing the depolymerized lignin mixture derived products; precipitating depolymerized lignin and solid residues from the depolymerized lignin; dissolving the precipitated depolymerized lignin and solid residues in acetone; and separating the depolymerized lignin from the solid residues by filtration producing a solid depolymerized lignin. The produced solid depolymerized lignin can be used in the production of lignin-based rigid polyurethane foam, a phenol formaldehyde resole and a lignin-based epoxy resin with a high percentage of bio-content (≥ 50 wt. %).
(FR) La présente invention concerne un procédé de dépolymérisation d'une charge d'alimentation comprenant de la lignine produisant des lignines dépolymérisées comprenant le chargement d'une charge d'alimentation, d'un catalyseur, un polyalcool et de l'eau dans un réacteur ; le chauffage du réacteur jusqu'à environ 150 à 300 °C pour dépolymériser la lignine produisant un mélange de lignine dépolymérisée ; l'arrêt de la réaction de dépolymérisation par refroidissement rapide avec de l'eau froide ; l'acidification/neutralisation des produits dérivés du mélange de lignine dépolymérisée ; la précipitation de la lignine dépolymérisée et des résidus solides à partir de la lignine dépolymérisée ; la dissolution de la lignine dépolymérisée précipitée et des résidus solides dans l'acétone ; et la séparation de la lignine dépolymérisée des résidus solides par filtration produisant une lignine dépolymérisée solide. La lignine dépolymérisée solide produite par le procédé de l'invention peut être utilisée dans la production de mousse de polyuréthane rigide à base de lignine, d'un résol phénol-formaldéhyde et d'une résine époxy à base de lignine avec un pourcentage élevé en contenu d'origine biologique (≥ 50 % en poids).
