Abstract

L'invention concerne une nouvelle composition de catalyseur. Selon l'invention, cette composition est caractérisée par une surface active d'environ 60 m**2/g et comprend de 1 à 99 % en poids d'un composant d'hydrogénation comportant du cuivre sous forme élémentaire ou sous forme de composé et de l'oxyde de zinc et de 1 à 30 % en poids d'un composant de silice. L'invention concerne finalement un procédé d'hydrogénation d'une charge contenant un polyglycolide conformément auquel on met la charge en contact avec le catalyseur précité dans des conditions d'hydrogénation.
