20090074644 | REDUCED TEMPERATURE CALCINING METHOD FOR HYDROGEN GENERATION - A method and apparatus are disclosed for regenerating calcium oxide used in the production of hydrogen gas. The method includes steps of: (a) streaming a solid reactant into an inlet port of a contactor vessel; (b) streaming a purge oxidant into an oxidant port of the contactor vessel to reduce a partial pressure of a gas over the solid reactant; (c) venting the gas from a gas port of the contactor vessel; and (d) removing the solid reactant from a discharge port of the contactor vessel. | 03-19-2009 |
20100221167 | GAS SEPARATION MEMBRANE COMPRISING A SUBSTRATE WITH A LAYER OF COATED INORGANIC OXIDE PARTICLES AND AN OVERLAYER OF A GAS-SELECTIVE MATERIAL, AND ITS MANUFACTURE AND USE - A gas separation membrane and a method of manufacturing such gas separation membrane that comprises a porous substrate treated with a layer of metal-coated inorganic oxide particles and with the layer of such metal-coated inorganic oxide particles being coated with an overlayer of a gas-selective material. | 09-02-2010 |
20110158879 | METHODS OF CONTROLLING HYDROGEN CONCENTRATIONS IN AN OFFGAS SYSTEM OF A NUCLEAR REACTOR BY PASSIVE AIR INJECTION - Example embodiments relate to methods of controlling hydrogen concentrations in an offgas system of a nuclear reactor by passive air injection. A method according to a non-limiting embodiment may include passively injecting ambient air through the hydrogen water chemistry system into an existing offgas line of the offgas system. The offgas line is configured to transport non-condensable gases, including hydrogen, from a condenser to a recombiner. As a result of the passive air injection, the combined flow of hydrogen and oxygen react in the recombiner to form water vapor, thereby reducing the hydrogen concentration of the offgas exiting the recombiner. | 06-30-2011 |
20120020862 | METHOD FOR THE REMOVAL OF HYDROGEN FROM A HYDROGEN SENSITIVE DEVICE BY MEANS OF A NON-EVAPORABLE YTTRIUM BASED GETTER ALLOY - Getter alloys particularly suitable for hydrogen sorption are described. The getter alloys include a first element consisting of yttrium or a yttrium equivalent mixture, the first element forming at least 30% by atoms of the alloy. A method for removing hydrogen from devices which are sensitive to the presence thereof and hydrogen-sensitive devices which contain the described getter alloys are also described. | 01-26-2012 |
20120263636 | Hydrogen Combustion Catalyst and Method for Producing Thereof, and Method For Combusting Hydrogen - The present invention is a hydrogen combustion catalyst including a catalyst metal supported on a carrier composed of an inorganic oxide, wherein a functional group having at the end thereof at least an alkyl group having three or less carbon atoms is bonded by substitution to each of a certain fraction or the whole of the hydroxyl groups on the surface of the carrier. The functional group bonded to each of a certain fraction or the whole of the hydroxyl groups on the surface of the carrier is preferably an organic silane. The hydrogen combustion catalyst according to the present invention is capable of maintaining the activity thereof even when a hydrogen-containing gas, a treatment object, contains a water content equal to or less than the saturated water vapor content and the reaction temperature is set at or around room temperature, namely, at 0 to 40° C. | 10-18-2012 |
20130183222 | PROCESS FOR WORKING UP AN EXHAUST GAS FROM A SYSTEM FOR PRODUCING HYDROXYLAMINE OR HYDROXYLAMMONNIUM SALTS - A process for working up an exhaust gas A from a system for producing hydroxylamine or hydroxylammonium salts by catalytic reduction of nitrogen monoxide with hydrogen, wherein the exhaust gas A comprises nitrogen monoxide, hydrogen, dinitrogen monoxide, nitrogen and ammonia, and at least some of the hydrogen present in the exhaust gas A is separated off from the exhaust gas A by means of a gas-tight membrane-electrode assembly which comprises at least one selectively proton-conducting membrane, a retentate side, a permeate side, and, on each side of the membrane, at least one electrode catalyst, wherein, on the retentate side of the membrane, at least some of the hydrogen is oxidized to protons at the anode catalyst and the protons, after crossing the membrane, are, on the permeate side, at the cathode catalyst according to
