A hydrogen-rich reformate gas generator (36), such as a mini-CPO, POX, ATR
or other hydrogen generator provides warm, dry, hydrogen-rich reformate
gas to a hydrogen desulfurizer (17) which provides desulfurized feedstock
gas to a major reformer (14) (such as a CPO) which, after processing in a
water-gas shift reactor (26) and preferential CO oxidizer (27) produces
hydrogen-containing reformate in a line (31) for use, for instance, as
fuel for a fuel cell power plant. The expensive prior art hydrogen blower
(30) is thereby eliminated, thus reducing parasitic power losses in the
power plant. The drier reformate provided by the small hydrogen generator
to the hydrogen desulfurizer favors hydrogen sulfide adsorption on zinc
oxide and helps to reduce sulfur to the parts per billion level.
