  • Patent number: 6406518
    Abstract: A process (and corresponding system) for separating a high purity gas (e.g. oxygen) from a feed gas stream (e.g. air) that includes heating the feed gas stream before passing the heated feed gas stream through a ceramic membrane to separate a gas component from the other components of the gas stream.
    Type: Grant

  • Patent number: 6402988
    Abstract: An exothermic reaction and an endothermic reaction are thermally combined in a reactor having at least one oxygen selective ion transport membrane that provides the exothermic reaction with oxygen from an oxygen-containing gas such as air. The thermal requirements of the endothermic reaction are satisfied by the exothermic reaction. Dependent on the reactor design employed, the exothermic and endothermic reactions may be gaseously combined.

  • Patent number: 6153163
    Abstract: A process to generate an enhanced output of a desired product from an ion transport reactor utilizes the reaction products from both the cathode side and the anode side of an oxygen selective ion transport ceramic membrane. An oxygen donating first feed stream containing the desired product in a chemically bound state is delivered to the cathode side while an oxygen accepting second feed stream is delivered to the anode side. Following chemical reactions on both the cathode side and the anode side, a desired product is recovered from a first product stream exiting from the cathode side and from a second product stream exiting from the anode side such that the sum of the desired product contained within the two product streams exceeds that attainable from either product stream alone.

  • Patent number: 6139810
    Abstract: A reactor comprising: a hollow shell defining a hermetic enclosure; a plurality of tube sheets disposed within said hermetic enclosure, a first one of said plurality of tube sheets defining a first chamber; at least one reaction tube each having a first end and an opposing second end, said first end being fixedly attached and substantially hermetically sealed to one end of said plurality of tube sheets and opening into said first chamber, the second end being axially unrestrained; each of said reaction tubes is comprised of an oxygen selective ion transport membrane with an anode side wherein said oxygen selective ion transport membrane is formed from a mixed conductor metal oxide that is effective for the transport of elemental oxygen at elevated temperatures and at least a portion of said first and second heat transfer sections are formed of metal; each of said reaction tubes includes first and second heat transfer sections and a reaction section, said reaction section disposed between said first and second
