<p>A method and apparatus for reducing the carbon monoxide content of a hydrogen rich gas including a catalyst bed (200) containing an oxidation catalyst (220), a porous tube (210) positioned substantially within the catalyst bed (200) for distributing an oxygen-containing stream (A) throughout the catalyst bed (200), and a cooling jacket (230) for maintaining operating temperature of the catalyst bed (200) uin a desired range. The porous tube (210) can be constructed as a sintered stainless steel tube or as an alumina tube or as any equivalent porous tube that is known to these skilled in the art to perform the objectives of this method and apparatus. The porous tube (210) is generally positioned along the length of the catalyst bed (200) in a manner that optimises dispersion of the oxygen-containing stream (A) throughout the catalyst bed (200). Operating temperature of the catalyst bed (200) is controlled by a cooling jacket (230) to form about 90 °C to about 180 °C, more preferably from about 90 °C to 150 °C. The cooling jacket (230) contains a circulating coolant that can be water, steam, air, or the hydrocarbon fuel to the fuel processor.</p> |
