Abstract | A method of producing hydrogen comprising: reacting water and a water-soluble oxygenated hydrocarbon having from 2 to 12 carbon atoms, where the water and the oxygenated hydrocarbon are gaseous wherein the pressure is from 1 to 54 bar, at a pH of from 4.0 to 10.0, at a temperature not greater than 450 °C, in the presence of a metal-containing catalyst such as herein described, wherein the catalyst comprises a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof in an amount of 0.25% to 50% by total weight of the catalyst wherein optionally alloyed or mixed with a metal selected from the group consisting of Group IB metals, Group IIB metals, Group VIIB metals, Group IVA metals, and Group VA metals in an amount not exceeding 30% of weight of the Group VIIIB transition metals. |
Full Text | A method of producing hydrogen from oxygenated hydro-carbon 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. A reactor (18) is disposed within a furnace (20). Liquid reactants are introduced into the reactor (18) via pump (16). Nitrogen supply (10) and hydrogen supply (12) are provided to maintain the overall pressure of the system and the partial pressure of hydrogen within the system chambers in and downstream of the reactor (18). Mass flow controllers (14) are provided to regulate the introduction of nitrogen and hydrogen into the system. A heat exchanger (22) is provided to reduce the temperature of the products exciting the reactor (18). The products are then swept into separator (24). Pressure regulator (28) and back-pressure regulator (26) serve to monitor and maintain the pressure of the system within the set value or range. WE CLAIM:- 1. A method of producing hydrogen comprising: reacting water and a water-soluble oxygenated hydrocarbon having from 2 to 12 carbon atoms, where the water and the oxygenated hydrocarbon are gaseous wherein the pressure is from 1 to 54 bar, at a pH of from 4.0 to 10.0, at a temperature not greater than 450 °C, in the presence of a metal-containing catalyst such as herein described, wherein the catalyst comprises a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof in an amount of 0.25% to 50% by total weight of the catalyst wherein optionally alloyed or mixed with a metal selected from the group consisting of Group IB metals, Group I IB metals, Group VI IB metals, Group IVA metals, and Group VA metals in an amount not exceeding 30% of weight of the Group VIIIB transition metals. 2. The method as claimed in Claim 1, wherein the water and the oxygenated hydrocarbon are reacted at a temperature of from 100°C to 300°C, and at a pressure where the water and the oxygenated hydrocarbon are gaseous. 3. The method as claimed in Claim 1, wherein the water and the oxygenated hydrocarbon are reacted at a temperature not greater than 400°C, at a pressure where the water and the oxygenated hydrocarbon remain condensed liquids. 4. The method as claimed in Claim 1, wherein the catalyst is alloyed with a metal selected from the group consisting of Group IB metals, Group IIB metals, Group VIIB metals, Group IVA metals, and Group VA metals. |
