  • Patent number: 9673465
    Abstract: The present invention provides a catalyst in which a reaction initiation temperature at which self-heating function is exhibited is low and which is capable of suppressing carbon accumulation even when a reaction is repeated. The catalyst of the present invention includes a CeZr-based oxide, silicon, and a catalytically active metal, wherein the CeZr-based oxide satisfies CexZryO2 (x+y=1) and the silicon satisfies molar ratios of 0.02?Si/Zr and 0.01<Si/(Ce+Zr+Si)<0.2. When the catalyst is used, a reduction temperature for generating initial oxygen deficiency can be decreased. Depending on the catalytically active metal, a reduction activation treatment can be performed even at about 20° C. without any need for heating. In a repeated hydrogen generating reaction, the deposition of carbon generated on the surface of the catalyst can be suppressed, and a decrease in catalytic activity can be prevented.

  • Patent number: 9669371
    Abstract: Systems, devices, and methods combine reactant materials and aqueous solutions to generate hydrogen. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Multiple inlets of varied placement geometries deliver aqueous solution to the reaction. The reactant materials and aqueous solution are churned to control the state of the reaction. The aqueous solution can be recycled and returned to the reaction. One system operates over a range of temperatures and pressures and includes a hydrogen separator, a heat removal mechanism, and state of reaction control devices. The systems, devices, and methods of generating hydrogen provide thermally stable solids, near-instant reaction with the aqueous solutions, and a non-toxic liquid by-product.

    Abstract: A method of purifying ammonia borane is provided in which crude ammonia borane is dissolved in an organic solvent, such as an ether, and mixed with a basic aqueous solution to form a two-phase system. The pH of the aqueous solution and the temperature are adjusted to increase the solubility of the impurities and decrease the solubility of the ammonia borane in the basic aqueous solution, without causing decomposition of the ammonia borane. The impurities are separated from the crude ammonia borane solution, the mixture is phase-separated and the dissolved ammonia borane is isolated from the organic solvent fraction. High purity ammonia borane is obtained.
