Disclosed are methods for generating propylene glycol, ethylene glycol and other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols from biomass using hydrogen produced from the biomass. The methods involve reacting a portion of an aqueous stream of a biomass feedstock solution over a catalyst under aqueous phase reforming conditions to produce hydrogen, and then reacting the hydrogen and the aqueous feedstock solution over a catalyst to produce propylene glycol, ethylene glycal and the other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols. The disclosed methods can be run at lower temperatures and pressures, and allows for the production of oxygenated hydrocarbons without the need for hydrogen from an external source.

I claim: 1. A method of generating ketones or alcohols, the method comprising the steps of:a. contacting a first catalytic material comprising one or more Group VIII metals with a first portion of an aqueous feedstock solution comprising water and at least one water-soluble oxygenated hydrocarbon having two or more carbon atoms under conditions sufficient to produce hydrogen; andb. reacting the hydrogen with a second portion of the aqueous feedstock solution over a second catalytic material, the second catalytic material different than the first catalytic material and comprising iron, ruthenium, copper, rhenium, cobalt, nickel, an alloy of at least two of the foregoing, or mixtures of at least two of the foregoing, under conditions sufficient to produce one or more ketones selected from the group consisting of acetone, propanone, butanone, pentanone, and hexanone, or one or more alcohols selected from the group consisting of methanol, ethanol, iso-propyl alcohol, propanol, butanol, pentanol, and hexanol.
