A process for hydrogenation of glycerol in which a feed comprising glycerol is contacted with a stream of a hydrogen-containing gas and subjected to hydrogenation in the vapour phase in the presence of a catalyst at a temperature of from about 160°C to about 260°C, a pressure of from about 10 to about 30 bar, a hydrogen to glycerol ratio of from 400:1 to about 600:1 and a residence time of from about 0.01 to about 2.5 secs.

L'invention concerne un procédé d'hydrogénation de glycérol dans lequel un flux d'alimentation comprenant du glycérol est mis au contact d'un flux gazeux contenant de l'hydrogène et soumis à une hydrogénation en phase vapeur, en présence d'un catalyseur, la température étant comprise entre environ 160 °C et environ 260 °C, la pression étant comprise entre environ 10 et environ 30 bars, le rapport entre l'hydrogène et le glycérol étant compris entre environ 400:1 et environ 600:1, et le temps de séjour étant compris entre environ 0,01 et environ 2,5 heures.
