Embodiments of a compact pressure swing reformer are disclosed. Certain embodiments have a construction comprising multiple rotating reformer beds, high temperature rotary valves at the bed ends, and E-seals to seal the beds to the valves. Several possible designs for introducing reactants into the beds also are disclosed. The multiple reformer beds are configured to provide for pressure equalization and 'steam push'. The compact pressure swing reformer is suitable for use in fuel cell vehicle applications.

Compact pressure swing reformer

The present invention provides a high capacity adsorbent for removing sulfur from hydrocarbon streams. The adsorbent comprises a composite material containing particles of a nickel phosphide complex NiP. The adsorbent is utilized in a sulfur removal process that does not require added hydrogen, and run at relatively low temperatures ranging from about 150&#xb0; C. to about 400&#xb0; C. The process of this invention enables 'ultra-deep' desulfurization down to levels of about 1 ppm and less.

The overall efficiency of a regenerative bed reverse flow reactor system is increased where the location of the exothermic reaction used for regeneration is suitably controlled. The present invention provides a method and apparatus for controlling the combustion to improve the thermal efficiency of bed regeneration in a cyclic reaction/regeneration processes. The process for thermal regeneration of a regenerative reactor bed entails

A method for producing a hydrogen containing gas for use in an internal combustion engine system is provided. The method includes cyclically operating at least two pressure swing reformer reactors such that one is reforming while another is regenerating, thereby producing a continuous stream of hydrogen containing gas. During engine operation exhaust gas is fed to the pressure swing reformer reactor that is undergoing regeneration, thereby supplying at least part of the heat for regeneration. Also, the hydrogen gas produced is used in at least one of (i) the engine; (ii) an engine exhaust treatment device; and (iii) a fuel cell.
