Abstract
A hydrogen-rich reformate gas generator (), such as a mini-CPO, POX, ATR or other hydrogen generator provides warm, dry, hydrogen-rich reformate gas to a hydrogen desulfurizer () which provides desulfurized feedstock gas to a major reformer () (such as a CPO) which, after processing in a water-gas shift reactor () and preferential CO oxidizer () produces hydrogen-containing reformate in a line () for use, for instance, as fuel for a fuel cell power plant. The expensive prior art hydrogen blower () 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.
