Reactor for generating hydrogen from metal hydride and water

Номер: GB2290784A
Принадлежит:

The reaction of metal hydride with water is utilised for the generation of hydrogen in a novel generator configuration which overcomes the problem associated with the expansion of the hydride upon its conversion to hydroxide or oxide when reacting with water. The hydride cartridge 10 is comprised of a structure of corrugated perforated sheet metal 13 and layers 12 of water wicking material having hydride granules 17 dispersed therein. The hydride cartridge is housed in a reactor to which liquid water is admitted in a controlled mode. As the water enters the reactor via tube 14 and reaches the cartridge via perforations 15 hydrogen is instantaneously generated by the hydride water reaction. The hydrogen generation continues as long as unreacted hydride remains and water is being admitted. As the reaction proceeds the volumetric expansion associated with hydride expansion is accommodated by compression of the corrugations of the sheet metal cartridge structure. The combination of the corrugated ...

A device for generating lighter-than-air gas to inflate a marker buoy or like item, for example in a "man-overboard" situation. The device includes separate chambers for the chemicals and the ambient water used in the reaction. The transfer of a significant quantity of water from the water chamber to the chamber housing the chemicals is automatically delayed until such time as sufficient water to complete the whole of the desired gas-generating reaction has been accepted into the water chamber. The control means for achieving this delay may take various forms. For example it could comprise a wick initially providing substantially the only water path from the water chamber to the reaction chamber housing the chemicals. Alternatively where there is an unrestricted passageway for a free flow of water between the two chambers, the control means could comprise a mass arranged to move automatically to reorientate the device from an initial position, in which the water chamber is at a lower level ...

A portable vapor-dispensing device is disclosed. The device comprises a housing (110), a fluid reservoir (200) for containing an evaporable fluid substance ("F"), a heating means, and a plume-emitting chimney (240). The heating means comprises a heating element (380) and a fluid passageway (320) which communicates with the fluid reservoir (200) and the plume-emitting chimney (240) and which provides a fluid-evaporation zone for the evaporable fluid substance ("F"). The fluid passageway (320) is disposed within the plume-emitting chimney (240). The heating element (380) is externally carried by the fluid passageway (320) and is disposed about the fluid-evaporation zone. The heating element, when energized, causes heat to pass radially through the sidewall of the fluid passageway (320), which in turn causes evaporation of the evaporable fluid substance ("F") from the fluid-evaporation zone. The chimney (240) emits a plume of the thus-evaporated substance, thereby providing an envelope of ...

An arrangement for carbonating a solution by pressurization of a defined spatial area in a container in which a carbonating mixture is combined with a solution. The container is typically filled with a solution to a demarcation defining a spatial area. Reactants, an acid and a base, evolve CO2 when reacted in a solution. The quantity of reactants added is designated so as to generate a quantity of CO2 which will increase the pressure in a defined spatial area and cause a quantity of CO2 to redissolve. The result of this arrangement is a solution supersaturated with CO2. The reaction chamber may also be divided into separate compartments with each compartment containing individual servings. Each compartment has an evacuation device allowing the contents of the compartment to be delivered for consumption without effecting the level of carbonation of the solution remaining in the other compartments of the container. The separate compartments of the container also allow the solution of each ...

An improved catalytic gas generator, of the type used, for example, in a monopropellant hydrazine rocket engine includes a dynamic catalyst bed retention device. The dynamic retention device comprises a compression band surrounding a generally cylindrical catalyst bed that is axially restrained at both ends. A torsional force is applied to the compression band, which converts the torsional force into a radially inwardly directed compression force. As voids develop in the catalyst bed upon repeated impulsing, the inwardly directed compressive force redistributes the catalyst bed so as to fill the voids. The retention device thus allows the catalyst bed to perform at peak efficiency yielding a gas generator that can be repeatedly pulsed with uniformly reproducible results.

Methods and systems for producing hydrogen from methane or other fuels that has lower input heat requirements than conventional steam reformation schemes are provided. The system has a reactor with a controlled feed of fuel, water/steam, CO and recycle gases. The methods generally use significantly high amounts of steam (water) and carbon monoxide (CO) in the feed that substantially enhances the reaction rate of the water-gas shift reaction, which transforms CO and HO to COand H. Since this reaction is exothermic, its enhancement alters the endothermic nature of the overall reforming process to the point where the overall reforming process is no longer endothermic. The CO requirements may be met in part with the reverse water-gas shift reaction from COproduced by the reactor. The lower heat requirements may be satisfied with renewable sources such as solar or from hydrogen produced by the system. 1.

The present application provides a high-gravity device for generating nano/micron bubble and a reaction system. In the device, the liquid phase is continuous phase and the gas phase is dispersed phase. A gas enters the interior of the device from a hollow shaft, and the gas is subjected to primary shearing under a shearing effect of aerating micropores to form bubbles; then, the bubbles rapidly disengage from the surface of a rotating shaft under the effect of the rotating shaft rotating at a high speed, and are subjected to secondary shearing under the high-gravity environment with the strong shearing force formed by the rotating shaft to form nano/micron bubbles. The device has the advantages of fastness, stability, and small average particle size. The average particle size of the formed nano/micron bubbles is between 800 nanometers and 50 microns, and the average particle size of the bubbles can be regulated in a range by adjusting the rotating speed of the rotating shaft.
