Title (EN) PROCESS FOR THE PREPARATION OF GLYCOLS
(FR) PROCÉDÉ POUR LA 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 comprising providing a feedstock comprising said one or more saccharides in a solvent to a reactor, said reactor having supported therein a heterogeneous hydrogenation catalytic composition and contacting the feedstock therein directly with said heterogeneous hydrogenation catalytic composition and concurrently with a retro-aldol catalyst composition in the presence of hydrogen, wherein said reactor operates in an essentially plug flow manner.
(FR) L'invention concerne un procédé continu pour la préparation d'éthylène glycol et de 1,2-propylène glycol à partir d'une matière de départ comprenant au moins un saccharide, ledit procédé consistant à placer une charge de départ comprenant ledit au moins un saccharide dans un solvant dans un réacteur, ledit réacteur comprenant en son sein une composition catalytique d'hydrogénation hétérogène, et à mettre la charge de départ en son sein directement en contact avec ladite composition catalytique d'hydrogénation hétérogène et simultanément avec une composition catalytique rétro-aldol en présence d'hydrogène, ledit réacteur fonctionnant selon un écoulement sensiblement en piston.
