Abstract
Disclosed is a method of producing hydrogen from oxygenated hydrocarbon reactants, such as methanol, glycerol, sugars (e.g. glucose and xylose), or sugar alcohols (e.g. sorbitol). The method takes place in the condensed liquid phase. The method includes the steps of reacting water and a water-soluble oxygenated hydrocarbon 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. The disclosed method can be run at lower temperatures than those used in the conventional steam reforming of alkanes.

A method of producing hydrogen via condensed-phase reforming, the method comprising:
- reacting water and a water-soluble oxygenated hydrocarbon, in the condensed phase, in the presence of a metal-containing catalyst, and wherein the catalyst comprises a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof.
A method of producing hydrogen comprising:
- reacting water and methanol at a temperature not greater than about 400° C., at a pressure where the water and the methanol remain condensed liquids, and in the presence of a metal-containing catalyst, wherein the catalyst comprises a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof, and the catalyst is adhered to a support.
