  • Microspheres for combined oxygen separation, storage and delivery
    Patent number: 5910238
    Abstract: An article for the separation, storage and delivery of substantially pure oxygen, comprises a closed walled, hollow container wherein at least a portion of at least one wall of the container is an oxygen separation material, providing a sole means for transporting substantially all oxygen into the container. An apparatus for the delivery of oxygen comprises means for transferring oxygen from a fluid containing oxygen to at least one such container at elevated temperature and pressure. The apparatus can provide means for transporting said the substantially pure oxygen-bearing container, means for storing said the container, and means for extracting oxygen from the container. A process includes filling the article with substantially pure oxygen, and, storing the substantially pure oxygen within the container for a selected period of time. The process may include releasing the oxygen from the container.
