  • Patent number: 8147598
    Abstract: A jacket material into which a gas adsorbing device and core material are inserted is decompressed in a vacuum chamber, the opening is sealed, and then the jacket material is exposed to the atmosphere. In the atmospheric pressure, a pressure of about 1 atm which is equivalent to the pressure difference between the inside and outside is applied to the jacket material of the heat insulator. The jacket material is made of a plastic laminated film and is deformed by pressure. A protruding portion is plunged into a container to drill through holes, and a gas adsorbent in the container communicates with the inside of the jacket material. Thus, both during holding and in applying to the vacuum heat insulator, the gas adsorbent can be applied to the vacuum heat insulator without degradation, and the high degree of vacuum can be kept for a long time.

  • Publication number: 20120055334
    Abstract: A method for removing negatively-charged gas molecules includes the steps of: adsorbing negatively-charged gas molecules by a substrate carrying a positively-charged substance or a positively-charged substance and a negatively-charged substance on the surface of the substrate or in a surface layer of the substrate; and desorbing the aforementioned negatively-charged gas molecules adsorbed on the aforementioned substrate, from the substrate using a fluid. According to the present invention, negatively-charged gas molecules are removed or detoxified by adsorbing the same by a substrate carrying a positively-charged substance, or a positively-charged substance and a negatively-charged substance, on the surface of the substrate. Thereby, it is possible to provide a simple process by which negatively-charged gas molecules are able to be effectively and economically removed or detoxified.

  • Patent number: 8123834
    Abstract: Novel metal organic framework (MOF) molecules and methods of synthesizing them are described. MOFs are organometallic crystalline structures that have high sorption capacity due to high surface area, tailorable selectivity, an inert nature, and thermal stability at high temperatures. MOFs may be used as sorbents in preconcentrators for analytical devices to provide orders of magnitude of improved sensitivity in analyte detection. MOFs are also useful as sorbents in new compact and portable micropreconcentrator designs such as a modified purge and trap system and a multi-valve microelectromechanical system (MEMS) to achieve high gain in analyte detection. Further, MOFs may be used as coatings for novel microstructure arrays in micropreconcentrators where the microstructures are designed to increase the surface area to volume ratio inside the micropreconcentrator while minimizing the pressure drop across the micropreconcentrator.

  • Publication number: 20120036999
    Abstract: A method of using a crystallographic framework of sterically bulky calixarene molecules to selectively separate and/or store volatile gas components. Sterically bulky calix[4]arenes or their derivatives form a crystalline lattice that has relatively large lattice voids, is nonporous, and is held together predominately by van der Waals forces. The calix[4]arene lattice can form a guest-host assembly by absorbing a desired volatile gas guest component into the crystalline lattice without any phase shift or other change to the lattice structure. The crystalline calixarene can also be desirably used to purify a gas mixture by removing one or more volatile gas contaminants or by removing and storing the desired volatile gas component. This method can preferably be used to purify a hydrogen gas stream by removing the carbon dioxide and carbon monoxide contaminants or to remove and store oxygen from the air or carbon dioxide and carbon monoxide from combustion gases.

  • Publication number: 20110072974
    Abstract: A flame-retardant hydrocarbon adsorption trap is adapted for mounting within an air intake tract. The traps includes a hydrocarbon vapor adsorbent media adapted to adsorb hydrocarbon vapors from an intake tract when an engine is not operating then later releasing the vapors when the engine runs. The trap includes at least two air permeable HCA media retention layers positioned in a spaced parallel relationship and forming a gap there-between into which hydrocarbon vapor adsorbent media is received. The retention layers are formed of a synthetic fiber media adapted to provide flame-resistant properties.

  • Publication number: 20110072967
    Abstract: The invention relates to compositions that can be used to adsorb low concentration, preferably, for example less than 15 ppm, of unwanted or target substances. Typically the absorbance can be from an enclosed vapor phase. Such absorbency is accomplished in a contained substantially enclosed gaseous volume or atmosphere using a composition comprising a cyclodextrin compound and a polyethylenimine that can have an absorbency capability for low concentrations of unwanted or target substances. Such absorbency can be obtained with thermoplastic materials used in the form of bulk polymer or a film, fiber, web, woven fabric, nonwoven fabric, sheet, packaging and other such structures including or surrounding the enclosed volume. The adsorbent of the invention is typically used in the context of an enclosed volume, also known as an enclosed ambient vapor phase that contains the adsorbent of the invention and the unwanted or target substances at a concentration that is not desirable.

  • Patent number: 7896953
    Abstract: A process and device to capture of CO2 at its originating source, such as a power plant, is disclosed. Absorbent material is recharged by desorbing CO2, so that it may be sequestered or used in another application. Continual recharging results in loss of absorbent surface area, due to pore plugging and sintering of particles. Calcium oxide or calcium hydroxide was immobilized to a fibrous ceramic-based fabric substrate as a thin film and sintered, creating an absorbent material. The samples were characterized, showing continuous cyclic carbonation conversions between about 62% and 75% under mild calcination conditions at 750° C. and no CO2 in N2. Under the more severe calcination condition at 850° C. and 20 wt % CO2 in N2, yttria fabric was superior to alumina as a substrate for carbon dioxide capture and the reactivity of the calcium oxide absorbent immobilized to yttria was maintained at the same level in the 12 cycles.

  • Publication number: 20110017070
    Abstract: A model of vessel installation and placement includes a shelf and a vessel installed under the shelf. There is at least one absorbing board equipped respectively on the shelf and arranged alternately. Absorbed boards attached to the absorbing boards are equipped to the bottom or the open of the vessel. Absorbing boards are equipped alternately to the shelf. And absorbed boards are equipped to the bottom or the open of the vessel and are attached to absorbing boards. Hence, when in use, absorbing boards on the shelf are attached to absorbed boards at the bottom or the open of the vessel, which enables that the bottom of the vessel faces up and the open of the vessel points down and is set under the shelf. This method can avoid accumulation of dust and moisture when the vessel is unused for a period of time and can keep clean of the internal vessel, so as to avoid that support frame or internal vessel is accumulated with moisture and dust and keep the vessel clean.

  • Patent number: 7875106
    Abstract: A method device and material for performing adsorption wherein a fluid mixture is passed through a channel in a structured adsorbent bed having a solid adsorbent comprised of adsorbent particles having a general diameter less than 100 um, loaded in a porous support matrix defining at least one straight flow channel. The adsorbent bed is configured to allow passage of a fluid through said channel and diffusion of a target material into said adsorbent under a pressure gradient driving force. The targeted molecular species in the fluid mixture diffuses across the porous support retaining layer, contacts the adsorbent, and adsorbs on the adsorbent, while the remaining species in the fluid mixture flows out of the channel.
