ABSTRACT:
Disclosed is a method of producing hydrocarbons from oxygenated hydrocarbon reactants, such as glycerol, glucose, or sorbitol. The method can take place in the vapor phase or in the condensed liquid phase (preferably in the condensed liquid phase). The method includes the steps of reacting water and a water-soluble oxygenated hydrocarbon having at least two carbon atoms, in the presence of a metal-containing catalyst. The catalyst contains a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof. These metals are supported on supports that exhibit acidity or the reaction is conducted under liquid-phase conditions at acidic pHs. The disclosed method allows the production of hydrocarbon by the liquid-phase reaction of water with biomass-derived oxygenated compounds.
