Patent ID: 7338644

Claim:
A fuel processor for converting a hydrocarbonaceous fuel into hydrogen and carbon dioxide comprising: (a) a vessel having an at least partly double-walled cylindrical side wall comprising an inner shell and an outer shell, and an outlet; (b) a first fluid flow path, defined between the inner shell and the outer shell of the side wall, having an inlet and an outlet; (c) an exothermic partial oxidation zone for converting the hydrocarbonaceous fuel into a product gas comprising carbon monoxide and hydrogen having an inlet and an outlet; (d) a steam generator; (e) a water-gas shift reaction zone having an inlet and an outlet and containing a catalyst suitable for the water-gas shift conversion reaction; (f) a second fluid flow path extending from the outlet of the exothermic partial oxidation zone, along the steam generator, to the inlet of the water-gas shift reaction zone; (g) a carbon monoxide removal zone having an inlet and an outlet, which zone contains a catalyst suitable for selectively oxidising carbon monoxide or for methanation of carbon monoxide; (h) a third fluid flow path extending from the outlet of the water-gas shift reaction zone, along the inner surface of the inner shell of the side wall of the vessel, to the inlet of carbon monoxide removal zone, which third fluid flow path is in heat-exchange contact with the first fluid flow path; and (i) a fourth fluid flow path extending from the outlet of the carbon monoxide removal zone to the outlet of the vessel, wherein the exothermic partial oxidation zone, the steam generator, the water-gas shift reaction zone, and the carbon monoxide removal zone are contained in the vessel.
