Abstract:
A method to produce hydrogen from a catalytic reformer by reforming volatile heterocyclic compoundswhich comprises: providing said volatile heterocyclic compounds, and producing a vapor containing said heterocyclic compounds and water vapor, and subjecting said vapor to a catalytic reformer to produce a gas containing hydrogen and carbon monoxide, and subjecting the previously reformed gas containing hydrogen and carbon monoxide to catalytic steam shifting to substantially convert said carbon monoxide to carbon dioxide, and vaporizing said heterocyclic compounds and water from sensible heat of the previously steam shifted gas containing remaining carbon monoxide to form heterocyclic vapor and water vapor to form steam shiftect gas reduced sensible heat, and scrubbing the previously reduced sensible heat steam shifted gas containing hydrogen and remaining carbon monoxide, from steam shifting, in a solvent capable of dissolving carbon monoxide to form a solvent containing dissolved carbon monoxide and a gas containing hydrogen substantially devoid of carbon monoxide, and separating the previously scrubbed gas containing hydrogen substantially devoid of carbon monoxide from the solvent containing dissolved carbon monoxide thereby producing a gas containing hydrogen substantially devoid of carbon monoxide.
