Abstract: A method of dehydrogenating an amine-borane using an acid-catalyzed reaction. The method generates hydrogen and produces a solid polymeric [R1R2B—NR3R4]n product. The method of dehydrogenating amine-boranes may be used to generate H2 for portable power sources.

Abstract: A gasification reactor apparatus (10) comprising a gasification vessel (12), a gas-fired combustion chamber (70) and a combination fan and cyclone unit (20) in an upper part (12′) of the vessel (12) with two functions: first, the fan (62, 64) impels incoming feedstock (14, 14′) centrifugally into contact with the hot inside surface of the vessel to produce rapid onset of gasification. Second, the unit (20) exerts a cyclonic motion on the product gas causing outward separation of particulate matter from the gas, which passes to the outlet via a path through the middle of the vessel (12).
Abstract: The manifold hydrogen generator units for automotive I. C. engines are intended to provide a supplementary hydrogen fuel supply for conventional automotive I. C. engines, in addition to any primary fuel including gasoline, gasohol or hydrogen.The hydrogen is produced in a three stage process starting with the conversion of water to steam by means of multiple coils of copper tubing closely fitted to the exhaust manifold(s) of the I. C. engine. The steam is directed into one or two reactor cylinders containing rotating wire brushes axially disposed within the reactor cylinder(s) which remove a portion of the oxygen through progressive oxidation of the iron wire brushes. Periodic forced purging of the wire brushes is provided by combined aeration and vibrating of the rotating brushes.A final reforming stage of the partially reformed steam/hydrogen flow is obtained by steel wool packs which are periodically replaced.
