  • Patent number: 7759287
    Abstract: A composition and method of storing and releasing fuel gas such as hydrogen, methane or natural gas is provided which utilizes lightly crosslinked high density polyethylene pellets. Fuel gas is stored by placing the pellets in a reaction chamber which is heated to a temperature slightly above the crystalline melting point of the pellets, followed by the introduction of fuel gas into the chamber. The fuel gas permeates the pellets and becomes contained therein upon cooling of the pellets under pressure. The fuel gas may be stored indefinitely in the pellets at ambient temperature. When release of the fuel gas is desired, the pellets are incrementally metered into a discharge chamber and are heated to a temperature above the crystalline melting point of the pellets under a pressure from about 5 to 200 psi such that the fuel gas is released from the pellets for use. The expended pellets may then be recycled for further fuel gas storage.

    Abstract: A method for storing natural gas by adsorption which comprises separating an available natural gas in an infrastructure side (10) into a low carbon number component mainly containing methane and ethane and a high carbon number component mainly containing propane, butane and the like, and storing the low carbon number component by adsorption in a first adsorption tank (16) and storing the high carbon number component by adsorption in a second adsorption tank (18). The method can solve the problem that the high carbon number component condenses within a pore of an adsorbing agent and hence the adsorption of the carbon number component, the main component of natural gas, is inhibited, and thus improves the storage density. Accordingly, the method can be used for ensuring a high storage density also for an available natural gas. An adsorbing agent for use in the method is also disclosed.

    Abstract: A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having one or more layers of absorbent material treated with a red blood cell lysing agent and a gelling agent. The effect of combining a lysing agent that thins menses or other blood-containing bodily fluids with a gelling agent that thickens menses or other blood-containing bodily fluids is enhanced agglomeration and increased viscosity of the blood-containing bodily fluids that come in contact with the treated material.

  • Publication number: 20030113538
    Abstract: A channelized sorbent material comprises porous sorbent particles characterized by an average pore diameter. Each sorbent particle has at least one interior channel of an average transverse dimension (i.e. transverse diameter) that is at least ten times larger than the average pore diameter of the porous sorbent particle. The interior channel may constitute a single cylindrical through-bore in the sorbent particle, or alternatively, an array of intersecting or non-intersecting channels. The porous sorbent particles preferably comprise bead activated carbon particles. Such channelized sorbent material is particular useful as sorbent media in an adsorption-desorption apparatus for storage and dispensing of a sorbable fluid.

  • Patent number: 6290753
    Abstract: In a method for storing hydrogen in a carbon material containing microstructures in the form of cones with cone angles being multiples of 60°, the carbon material is introduced in a reaction vessel which is evacuated while the carbon material is kept at a temperature of 295-800 K, after which pure hydrogen gas is introduced in the reaction vessel, the carbon material being exposed to a hydrogen gas pressure in the range of 300-7600 torr such that the hydrogen gas is absorbed in the carbon material, and after which the reaction vessel is left at the ambient temperature with the carbon material under a fixed hydrogen gas pressure. For use the hydrogen is released in the form of a gas from the carbon material either at ambient temperature or by heating the carbon material in the reaction vessel.

  • Patent number: 6066592
    Abstract: A gas separator includes a porous substrate having fine pores opened on its surface and a metal for separating a gas, the porous substrate having fine pores having an average diameter of 0.1-3.0 .mu.m and a porosity of 25-45%, and the metal for separating a gas being filled into the pores in the porous substrate to close them. A gas separation film seldom exfoliates from the porous substrate, and the gas separator is excellent in durability in comparison with a conventional gas separator.

  • Patent number: 5888925
    Abstract: The present invention is a hydrogen getter and method for formulating and using the getter. This getter effectively removes hydrogen gas typically present in many hermetically-sealed electronic applications where the presence of such gas would otherwise be harmful to the electronics. The getter is a non-organic composition, usable in a wide range of temperatures as compared to organic getters. Moreover, the getter is formulated to be used without the need for the presence of oxygen. The getter is comprised of effective amounts of an oxide of a platinum group metal, a desiccant, and a gas permeable binder which preferably is cured after composition in an oxygen-bearing environment at about 150 to about 205 degrees centigrade.

  • Patent number: 5837741
    Abstract: A method of making a microporous carbon material which includes providing a precursor selected from the group consisting of crystalline salts of aromatic sulfonates and nonporous polymeric salts. Prior to carbonization, the precursor is treated by ion exchange or other conventional processes to introduce a metal such as iron, nickel and cobalt into the precursor. Heat treatment of such composite precursors in the temperature range of 350.degree. to 850.degree. C. in an inert oxygen free atmosphere for a sufficient time promotes thermally induced hydrogen abstraction and rearrangement of BSUs which result in the formation of a composite, carbonaceous microporous material which contains a metal component, and has a pore size distribution in the range of about 4-15 .ANG. A. The structural and storage characteristics of the microporous carbon materials are also disclosed.

  • Patent number: 5385876
    Abstract: A highly microporous adsorbent material is formed as a composite of a natural or synthetic clay or clay-like mineral matrix intercalated with an active carbon. The mineral is prepared and selected to have a selected interlayer spacing between microcrystalline sheets. An organic polymeric precursor is contacted therewith to fill the matrix interstices. Then the precursor is polymerized and carbonized to yield the adsorbent material in which the carbon is intercalated into the mineral matrix. The mineral can be naturally occurring smectite or synthetic hydrotalcite.

  • Patent number: 5292707
    Abstract: Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by raising the density of the polymer precursor of the carbon molecular sieve through adjustment of the conditions for suspension polymerization of vinylidene chloride.

    Abstract: Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by impregnating a polymer precursor of the carbon molecular sieve with additional monomers and polymerizing the monomers before carbonizing the precursor.
