Title (EN) PROCESS FOR THE PREPARATION OF GLYCOLS
(FR) PROCÉDÉ DE PRÉPARATION DE GLYCOLS
Abstract:
(EN) The invention provides a continuous process for the preparation of ethylene glycol and 1, 2-propylene glycol from starting material comprising one or more saccharides, said process being carried out in a reactor system comprising a reactor vessel equipped with an external recycle loop and said process comprising the steps of: i) providing the starting material in a solvent, via an inlet, to the external recycle loop and contacting it therein with a retro-aldol catalyst composition to provide an intermediate stream; ii) then contacting said intermediate stream with hydrogen in the presence of a hydrogenation catalyst composition in the reactor vessel; iii) withdrawing a product stream comprising glycols from the reactor vessel; iv) providing a portion of said product stream, via an outlet, for separation and purification of the glycols contained therein; and v) recycling the remainder of said product stream via the external recycle loop.
(FR) L'invention concerne un procédé continu de préparation d'éthylène glycol et de 1,2-propylène glycol, à partir d'un matériau de départ comprenant un ou plusieurs saccharides, lequel procédé est exécuté dans un système de réacteur comportant une cuve de réacteur équipée d'une boucle de recyclage externe et comprend les étapes suivantes consistant à : i) fournir le matériau de départ dans un solvant, par le biais d'un orifice d'entrée, à la boucle de recyclage externe et le mettre en contact dans celle-ci avec une composition catalytique de rétroaldolisation afin de fournir un flux intermédiaire ; ii) puis mettre en contact ce flux intermédiaire avec de l'hydrogène, en présence d'une composition de catalyseur d'hydrogénation, dans la cuve de réaction ; iii) retirer de la cuve du réacteur un flux de produit comprenant des glycols ; iv) fournir une partie de ce flux de produit, par le biais d'un orifice de sortie, à des fins de séparation et purification des glycols contenus dans celui-ci ; et v) recycler le reste du flux de produit par le biais de la boucle de recyclage externe.
