    Abstract: A distillate fuel steam reformer system in which a fuel feed stream is first separated into two process streams: an aliphatics-rich, sulfur-depleted gas stream, and an aromatics- and sulfur-rich liquid residue stream. The aliphatics-rich gas stream is desulfurized, mixed with steam, and converted in a reforming reactor to a hydrogen-rich product stream. The aromatics-rich residue stream is mixed with air and combusted to provide heat necessary for endothermic process operations. Reducing the amounts of sulfur and aromatic hydrocarbons directed to desulfurzation and reforming operations minimizes the size and weight of the overall apparatus. The process of the invention is well suited to the use of microchannel apparatuses for heat exchangers, reactors, and other system components, which may be assembled in slab configuration, further reducing system size and weight.

  • Patent number: 7128768
    Abstract: 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.
