The method for generating a hydrogen-rich stream from hydrocarbon fuels, ultimately to produce hydrogen gas, involves the following two steps performed in a cyclic fashion: (1) pyrolysis of the hydrocarbon fuel to obtain a carbon-rich fraction and a hydrogen-rich fraction; and (2) oxidation of the carbon-rich fraction, or a portion of it, for heat generation. The method involves the following optional steps: (3) steam gasification of part of the carbon-rich fraction to produce additional amounts of hydrogen and carbon monoxide; (4) water-gas shift reaction to convert carbon monoxide to carbon dioxide with the simultaneous formation of additional amounts of hydrogen; and (5) steam reforming of light hydrocarbons that may be produced in step (1) to produce more hydrogen and carbon monoxide.

Pyrolysis-based fuel processing method and apparatus

Solid waste resource recovery in space is effected by pyrolysis processing, to produce light gases as the main products (CH, H, CO, CO, HO, NH) and a reactive carbon-rich char as the main byproduct. Significant amounts of liquid products are formed under less severe pyrolysis conditions, and are cracked almost completely to gases as the temperature is raised. A primary pyrolysis model for the composite mixture is based on an existing model for whole biomass materials, and an artificial neural network models the changes in gas composition with the severity of pyrolysis conditions.
