Definitions

  • This invention is directed towards hollow glass microspheres and a process of using the microspheres as part of a hydrogen storage system.
  • the hollow glass microsphere wall defines a series of pores. The pores facilitate the placement of a hydrogen storage material within the interior of the hollow glass microsphere.
  • the porosity of the hollow glass microspheres can thereafter be modified by either altering or reducing the overall pore size or by coating the individual hollow glass microspheres so as to maintain the hydrogen storage material within a sealed interior of the hollow glass microsphere.
  • the coating and/or the controlled pore size enables the selective absorption of hydrogen gas through the walls of the hollow glass microsphere while isolating the hydrogen storage material encapsulated therein from other external gases and fluids.
  • the hollow glass microspheres can thereafter be subjected to variations in temperature, pressure, or other release stimulus triggers to bring about the release of hydrogen gas. Once dehydrided, the hollow glass microspheres and hydrogen storage material can be reused so as to once again selectively absorb hydrogen gas.
  • HGMs hollow glass microspheres
  • the production of hollow glass microspheres has been described in U.S. Pat. No. 3,365,315 (Beck); U.S. Pat. No. 4,661,137 (Garnier); and U.S. Pat. No. 5,256,180 (Garnier), and which are incorporated herein by reference.
  • U.S. Pat. No. 4,842,620 (PPG Industries) is directed to non-crystalline silica fibers having porous walls which are used in gas separation.
  • the fibers described in this application have different physical characteristics than microspheres and which makes fibers less desirable with respect to hydrogen separation and storage capabilities.
  • U.S. Pat. No. 6,358,532 (CaP Biotechnology, Inc.) uses porous-wall hollow glass microspheres for cell clustering and biomedical uses.
  • the porous-wall structures are designed to readily release microsphere contents when present within a biotic system.
  • the microspheres are used to provide a substrate to support cell growth within the porous-wall structure.
  • HGM hollow glass microsphere
  • HGM hollow glass microsphere
  • a hollow glass microsphere having a diameter range of between about 1.0 to about 140 microns, a density of about 0.05 gm/cc to about 0.50 gm/cc, and having a porous-wall structure having wall openings with an average pore size which may range from about 10 to about 1000 angstroms, and which contains within an interior of the hollow glass microsphere a hydrogen storage material, the exterior wall of the hollow glass microsphere containing a barrier coating sufficient to prevent gaseous or liquid contaminants from entering an interior of the HGM while permitting the passage of hydrogen gas through the exterior wall.
  • HGM hollow glass microsphere
  • FIG. 1 is a cross sectional view of a hollow glass porous-wall microsphere containing a hydrogen storage material within the interior of the microsphere.
  • FIG. 2 is a cross sectional view similar to FIG. 1 showing a microsphere having an exterior coating.
  • the hollow glass microspheres of the present invention are prepared using a special glass composition which after appropriate heat treatment separates into two continuous glass phases.
  • one of the phases is rich in silica, while the other is an extractable phase.
  • the extractable phase is preferably present in an amount of at least about 30 weight percent of the total glass composition.
  • other porous glass compositions may be used.
  • the extractable phase of the glass composition preferably includes boron-containing materials such as borosilicates or alkali-metal borosilicates. Suitable borosilicates and alkali-metal silicates may be found in reference to the teachings of U.S. Pat. No. 4,842,620 directed to leachable glass fiber compositions and which is incorporated herein by reference.
  • the extractable and non-extractable glass components are mixed, melted, quenched, and crushed to a fine glass powder consisting of individual glass particles having a particle size of about 5 to 50 microns.
  • the individual glass particles are then reheated using a gas/oxidizer flame.
  • the glass is raised to a temperature where a latent blowing agent within the glass, such as alkali sulfate along with various hydrates, carbonates, and halides, the selection and use of which are well known in the art, causes a single bubble to nucleate within each particle of glass.
  • a latent blowing agent within the glass such as alkali sulfate along with various hydrates, carbonates, and halides, the selection and use of which are well known in the art, causes a single bubble to nucleate within each particle of glass.
  • the glass particle temperature increases by exposure to the flame, the glass particle reaches a viscosity where the particle transforms to a sphere due to the surface tension forces.
  • the resulting hollow glass microspheres have densities in the range of about 0.05 gm/cc to about 0.5 gm/cc and diameters may range between about 1 to about 140 microns.
  • the hollow glass microspheres may be separated on the basis of density so as to select and segregate the hollow glass microspheres according to desired densities. Additionally, it is possible to separate the HGMs according to the microsphere diameter.
  • the resulting hollow glass microspheres have a glass wall composition in which the glass is essentially homogeneous.
  • the hollow glass microspheres may be heat treated to enhance the glass-in-glass phase separation by mixing the hollow glass microspheres with carbonaceous materials and heating in the absence of oxygen to the desired temperature region.
  • the homogeneous glass separates into two continuous glass phases: one extractable and the other rich in silica.
  • the extractable phase is readily leachable using strong mineral acids which results in the formation of wall pores within the remaining silica-rich phase. Suitable mineral acids and methods for leaching the glass may be seen in reference to U.S. Pat. No. 4,842,620 which is incorporated herein by reference.
  • the resulting hollow glass microspheres exhibit a high degree of cell wall porosity.
  • porosity means a series of pores and similar openings which either directly or indirectly define a series of passageways which provide communication between the interior and the exterior of the hollow glass microsphere.
  • An average cell wall porosity of about 10 angstroms to about 1000 angstroms can be achieved using this technology.
  • the cell wall porosity is dependent upon the percentage of extractable components formulated into the special glass composition used in the formation of the HGM and the degree of heat treatment employed. The duration and severity of the extraction process also can have some influence on the characteristics of the resulting cell wall pores including size and density of pores formed.
  • Microsphere 10 comprises a glass wall having an exterior surface 12 and an interior surface 14 .
  • the microsphere 10 further defines a hollow cavity 16 within the interior of the microsphere.
  • a plurality of pores 20 are defined within the glass wall of the microsphere.
  • a number of the pores 20 provide for communication between an exterior of the hollow glass microsphere and the interior cavity 16 of the hollow glass microsphere.
  • a hydrogen absorption material 30 Present within the hollow cavity 16 is a hydrogen absorption material 30 . The placement of the hydrogen storage material within the cavity 16 is provided in greater detail below.
  • the porous-wall hollow glass microspheres can be filled with a hydrogen absorbent such as palladium.
  • a hydrogen absorbent such as palladium.
  • palladium chloride can be forced through the porous glass walls using pressure.
  • hydrogen is then introduced under pressure to reduce the palladium chloride to palladium metal.
  • heat and vacuum drying may be used to remove any residual hydrochloric acid or water. This process can be repeated through several cycles to increase the amount of palladium ultimately encapsulated within the hollow glass microsphere.
  • the porosity of the hollow glass microsphere wall can be altered or reduced by additional heat treatment.
  • the pores can be effectively sealed by applying a coating material 40 such as tetraethyl orthosilicate solution and as illustrated in FIG. 2 .
  • the coating material can be formulated to permit the diffusion of hydrogen while excluding other gases.
  • the resulting hollow glass microsphere containing a hydrogen absorbent offers numerous advantages for use with hydrogen absorbing technologies. For instance, when palladium metal and other metal hydrides are used in a hydrogen absorption/desorption process, the hydrogen storage material tends to fracture into smaller particles or “fines.” The resulting fines can clog filters, limiting gas flow through the filtration bed in hydrogen separation devices, and/or blocking gas flow in hydrogen storage devices resulting in an overall loss of efficiency of the hydrogen absorption/desorption system. However, when encapsulated within the hollow glass microsphere, the resulting fines are contained within the hollow glass microsphere and continue to function in an absorption/desorption capacity.
  • HGMs having a sufficiently small pore size such that gaseous poisons which may interfere with the hydrogen absorbing material are physically excluded from entry into the interior of the HGM.
  • the HGM functions as a selective membrane which permits the flow of hydrogen gas into and out of the hollow glass microsphere while preventing the entry of larger gaseous or liquid molecules.
  • porous-wall hollow glass microsphere structure allows hydrogen gas to enter and exit the microsphere at much lower pressures and temperatures. Consequently, less strenuous rehydriding/dehydriding conditions can be employed using the porous-wall structure as a conduit to enable the passage of hydrogen gas through the wall of the glass microsphere.
  • barrier coatings may be selected for special properties so as to provide for selective membrane properties.
  • One such coating material is a sol gel material having a sufficiently defined pore structure that provides for a barrier against gaseous poisons while permitting the flow of hydrogen gas therethrough.
  • sol gel material may be found in reference to the commonly assigned U.S. Pat. No. 5,965,482, and which is incorporated herein by reference.
  • the hollow glass microspheres containing therein a hydrogen storage material, offer additional advantages within the hydrogen storage technology field.
  • the hollow glass microspheres used in accordance with the present invention may have diameters of between about 1 micron to about 140 microns. Given the size and selectable particle densities, the resulting hollow glass microspheres have fluid-like properties which make the hollow glass microspheres suitable for easier transport and bulk storage. For instance, transportation of large quantities of the filled hollow glass microspheres may be made utilizing existing pipelines used to convey the supplies of petroleum products and/or natural gas.
  • the transport is much safer in that the hydrogen is stored within a plurality of discrete hollow glass microsphere vessels.
  • the dangers associated with the storage of a comparable volume of hydrogen gas is greatly lessened since the volume is now distributed within a large number of individual hollow glass microsphere vessels.
  • the individual hollow glass microspheres provide an enhanced level of safety against explosion and fire in that there are no exposed large volumes of hydrogen gas. For example, a leak or release of HGMs containing releasable hydrogen has a much reduced threat of explosion or fire since no free hydrogen is available. Even if released into flame or high temperature conditions, the insulating properties of the hollow glass microspheres are such that the net result is a series of very small releases of hydrogen gas as opposed to a release of a single large volume of hydrogen gas.
  • palladium represents one hydrogen storage material which may be incorporated into the interior of the hollow glass microspheres
  • a variety of other hydrogen storage materials are also suitable for use within the interior of a porous-wall hollow glass microsphere.
  • Such materials include sodium aluminum hydride, lithium aluminum hydride, titanium aluminum hydride, complex hydrides, and various fused or hybrid hydrogen storage materials such as those described in commonly assigned PCT application PCT/US03/34980 which is incorporated herein by reference, and various catalyzed borohydrides as described in commonly owned U.S. provisional application entitled “Catalyzed Borohydrides For Hydrogen Storage having Attorney Docket No. WSR-78-P filed on Aug.
  • hollow glass microspheres can be utilized to provide a “protective environment” for reactive hydrides or other hydrogen storage materials which occupy the hollow interior of the porous hollow glass microsphere.
  • the use of the hollow glass microspheres greatly simplifies commercial recharging of the spent hydrogen storage material.
  • the hollow glass microspheres containing the hydrogen storage material are used to power a device, the spent HGM may be removed during a refueling operation and subsequently recharged.
  • the HGMs having a hydrogen storage material can be utilized in various environments such as a hydrogen-powered motor vehicle. To the extent the vehicle only needs to provide for a hydrogen release mechanism, the mechanics and operation of the vehicle may be greatly simplified. Upon refueling with a fresh supply of HGMs (containing hydrided hydrogen storage material) the spent HGMs are simply removed for subsequent rehydriding.
  • a hollow glass microsphere may be simplified by selection of an appropriate hydrogen storage material to serve as the source of the nucleating gas.
  • a hydrogen storage material which, when heated, may release hydrogen or other inert gas that may be used as the blowing agent for the resulting microsphere.
