  • Compact pressure swing reformer
    Patent number: 9687803
    Abstract: 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.

  • Electric power generation with heat exchanged membrane reactor
    Publication number: 20050109037
    Abstract: This invention is directed to a heat exchanged membrane reactor for electric power generation. More specifically, the invention comprises a membrane reactor system that employs catalytic or thermal steam reforming and a water gas shift reaction on one side of the membrane, and hydrogen combustion on the other side of the membrane. Heat of combustion is exchanged through the membrane to heat the hydrocarbon fuel and provide heat for the reforming reaction. In one embodiment, the hydrogen is combusted with compressed air to power a turbine to produce electricity. A carbon dioxide product stream is produced in inherently separated form and at pressure to facilitate injection of the CO2 into a well for the purpose of sequestering carbon from the earth's atmosphere.
