Beschreibung
Zusammenfassung:	The present invention describes a process for the production of propylene glycol from glycerol, the transformation of purified glycerol to propylene glycol being carried out by means of a reaction of hydrogenolysis, in the liquid phase, where the two stages of the reaction take place simultaneously and in one and the same reactor (1) under specified conditions of temperature and pressure, and the effluent from the fixed-bed reactor (1) is led to subsequent process stages that comprise separation and purification.
