Abstract: It is disclosed a process for producing a low boiling mixture comprising ethylene glycol and propylene glycol from a liquid sugar stream derived from a ligno-cellulosic biomass feedstock. The liquid sugar stream is catalytically converted in the presence of hydrogen to a mixture, which is separated into at least a high boiling mixture, comprising glycerol, and the low boiling mixture. The high boiling mixture is converted to hydrogen by reforming and the reforming hydrogen is used in the catalytical steps. Preferably, all the hydrogen used in the conversion process is generated by aqueous phase reforming of the high boiling polyols mixture.
