Abstract
The present invention discloses a process for the selective hydrogenation of glycerol in the liquid phase to produce 1- and 2-propanols in high yields as the major organic products. The process comprises subjecting a glycerol stream having at least 30% by weight water to a combination of low pressure and high temperature hydrogenation conditions in the presence of a promoted or un-promoted skeletal copper catalyst.
