ABSTRACT:
The invention relates generally to the production of oxygenated hydrocarbons such as lower alcohols and more preferably 1,2-propanediol. More particularly, this invention comprises a single-step catalytic process for the catalytic production of lower alcohols such as methanol, ethanol, ethylene glycol and 1,2-propanediol from glycerol in aqueous medium. The catalyst comprises a metal selected from the Group VIII transition metals, preferably platinum, alloys thereof and mixtures thereof and a microporous carrier, preferably a faujasite-type zeolite.
