  • Patent number: 7766986
    Abstract: The present invention is an improved process for the storage and delivery of hydrogen by the reversible hydrogenation/dehydrogenation of an organic compound wherein the organic compound is initially in its hydrogenated state. The improvement in the route to generating hydrogen is in the dehydrogenation step and recovery of the dehydrogenated organic compound resides in the following steps: introducing a hydrogenated organic compound to a microchannel reactor incorporating a dehydrogenation catalyst; effecting dehydrogenation of said hydrogenated organic compound under conditions whereby said hydrogenated organic compound is present as a liquid phase; generating a reaction product comprised of a liquid phase dehydrogenated organic compound and gaseous hydrogen; separating the liquid phase dehydrogenated organic compound from gaseous hydrogen; and, recovering the hydrogen and liquid phase dehydrogenated organic compound.

  • Patent number: 7396381
    Abstract: The present invention is directed to improvements in storage and delivery systems that allow for rapid fill and delivery of gases reversibly stored in a nonvolatile liquid medium, improvements in delivery and purity of the delivered gas. The low pressure storage and delivery system for gas which comprises: a container having an interior portion containing a reactive Lewis basic or Lewis acidic reactive liquid medium that is reversibly reacted with a gas having opposing Lewis acidity or basicity; a system for transferring energy into or out of the reactive liquid medium; or, a product gas purifier (e.g. a gas/liquid separator); or both.
