<p>1451408 Preparation of hydrogen SUN VENTURES Inc 19 Aug 1974 [5 Nov 1973] 36365/74 Heading C1A Hydrogen is made by the dissociation of steam into hydrogen and oxygen at a temperature above 1,500‹ C., especially 2,000‹ to 2,200‹ C., and passing the dissociated steam through a first chamber having a wall in common with a second chamber, said wall being made of a refractory oxide, especially zirconia, permeable to oxygen, and through which oxygen from the dissociated steam diffuses at above 1,500‹ C., sweeping the second chamber with gas to remove the permeated oxygen, and cooling the gaseous effluent from the first chamber to yield a hydrogen-rich stream. A reducing gas, suitably producer gas, may be used for the sweeping, and the oxidized producer gas may be used as a source of fuel in a preheater for the steam.</p> |
