<p>The method for generating a hydrogen-rich stream from hydrocarbon fuels (1), ultimately to produce hydrogen gas (13), involves the following two steps performed in a cyclic fashion: pyrolysis of the hydrocarbon fuel (1) to obtain a carbon-rich fraction (6) and a hydrogen-rich fraction (4); and oxidation of the carbon-rich fraction (6), or a portion of it, for heat generation. The method involves the following optional steps: steam gasification of part of the carbon-rich fraction to produce additional amounts of hydrogen and carbon monoxide; water-gas shift reaction to convert carbon monoxide to carbon dioxide with the simultaneous formation of additional amounts of hydrogen; and steam reforming of light hydrocarbons that may be produced in the first step to produce more hydrogen and carbon monoxide.</p> |
