Disclosed is a process for preparing ethylene glycol using cellulose, which comprises the catalytic conversion of cellulose into ethylene glycol using multi-metal catalyst at 120-300°C and 1-12MPa H2 under hydrothermal condition, wherein the multi-metal catalyst uses one or more transition metals of groups 8, 9 and 10 selected from iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium and platinum and one or more components selected from the metallic state, carbide, nitride or phosphide of molybdenum and/or tungsten as active components.

La présente invention concerne un procédé d'élaboration d'éthylène-glycol à partir de cellulose par conversion catalytique de cellulose en éthylène glycol au moyen d'un catalyseur multi-métallique dans des conditions hydrothermales de températures et de pression de 120°C à 300°C et 1MPa à 12MPa. En l'occurrence, les composants actifs mis en oevre dans le catalyseur multi-métallique sont, d'une part un ou plusieurs métaux de transition des groupes 8, 9 et 10 choisis dans l'ensemble formé par le fer, le cobalt, le nickel, le ruthénium, le rhodium, le palladium, l'iridium et le platine, et d'autre part un ou plusieurs composants choisis dans l'ensemble formé par les carbures, nitrures ou phosphures de molybdène et/ou de tungstène à l'état métallique.
