  • Publication number: 20150144037
    Abstract: The present invention is related to the synthesis of a nano-hybrid catalyst made of carbon nanotubes and metal ferrite materials for the removal of NOx compounds, which are emitted from stationary sources, through an ammonia selective catalytic reduction process. Weight ratios of carbon nanotube (x) to metal ferrite (y) is preferably about (x/y) 0.1 to 10. The present invention is also directed to the synthesis of a nano-hybrid catalyst to improve the efficiency of the conventional NOx reduction process at lower reaction temperatures. By use of the preferred nano-hybrid catalyst, it is possible to locate a selective catalytic reduction (SCR) unit capable of operating at lower temperatures, e.g., below 260° C., and from about 50° C. to about 250° C., after the desulfurizer and the particle removal equipment. With the exhaust gas cleaner, the lifetime of the catalyst can be increased. This nano-hybrid catalyst provides higher NOx removal efficiencies at low temperatures, typically from about 50° C.

  • Patent number: 9011727
    Abstract: Blending an electrically active, anodically coloring, electrochromic polymer with a non-electrochromic, non-electrically conductive binder polymer greatly enhances the performance of the anodically coloring, electrochromic polymer in an electrochromic device over time. In addition to improved physical characteristics of the blend, e.g., film build, durability etc, the coloristic properties, including color space and color strength, of the device comprising the blend are more durable than when using the neat polymer, and in certain instances, the color space and color intensity provided by the blend is superior to that available from the neat polymer.

    Abstract: An identification label changes color in an irreversible manner once put into contact with water/humidity. The label has a water-absorbable paper-based substrate having a surface on which an ink zone formed by printing of water-repellent or hydrophobic ink thereon and an opposite second surface on which a coating layer is formed. The ink zone has a color substantially identical to color of the substrate. The coating layer contains water soluble substance, which dissolves into water to form a solution that, once being absorbed by the substrate, changes the color of the substrate, the color of the solution being different from that of the substrate. A layer of adhesive is formed below the coating layer. Alternatively, the coating layer is formed on a surface of a double-sided adhesive layer and is bonded to a surface of the substrate opposite to the surface on which the ink zone is formed.

    Abstract: The purpose of the invention described in this document is to disclose a novel method using mixtures to change the viscosity of both light and heavy petroleums, by decreasing or increasing said viscosity. The methods derived from this invention are useful at ambient temperature and atmospheric pressure. The active component of the invention is dopamine, a compound that combined with other substances enables a change in the fluidity properties of petroleum, an increase in the electric charge properties of the mixtures and solutions and the dissolution of insoluble compounds in water or aqueous solutions. Some of the mixtures of this invention have been applied to modifying proton mobility, whereby significant increases in particular caused by the presence of metals chosen to bring about this purpose, can be detected within these mixtures, by measuring the electric charge.

  • Patent number: 6911069
    Abstract: Iodine or iodophor stain resistance is imparted to a surface by applying a hardenable coating composition containing an effective amount of a reducing agent having a redox potential sufficient to decolorize an iodine or iodophor stain. The reducing agent reacts with triiodide anion in the stain to change the stain coloration from a yellowish hue (e.g., yellow-white, yellow or brown) towards a lighter hue (e.g., pale yellow, white or transparent). This decolorization reaction takes place over a period of minutes, hours or days, and preferably can eventually cause the stain to disappear.

  • Patent number: 6863988
    Abstract: Monolayer packages comprised of an oxygen scavenging composition suitable for direct contact with package contents and recycle with other polyester bottles are disclosed. The oxygen scavenging composition is comprised of a modified copolymer which is comprised of predominantly polyester segments and an oxygen scavenging amount of oxygen scavenging segments. The polyester segments comprise segments derived from typical bottling and packaging polyesters such as PET and PEN. Use of these oxygen scavenging copolymers in bottles provides a clear and rigid monolayer bottle similar in appearance to unmodified polyester bottles. In a series of preferred embodiments, bottles fabricated with the oxygen scavenging copolymers of this invention are over 99 wt % PET and contain less than 50 ppb of extractable components.

  • Patent number: 6821594
    Abstract: The oxygen-absorbing label of the present invention has a laminated structure successively comprising a base layer having a release adhesive layer on its surface, an oxygen-absorbing sheet made from an oxygen-absorbing resin comprising a thermoplastic resin and an oxygen absorbent blended therein, and an air-permeable layer. The air-permeable layer is bonded to the base layer at a position surrounding an outer periphery of the oxygen-absorbing sheet. The air-permeable layer comprises (A) a water-resistant moisture-permeable resin film having a water pressure resistance of 2,000 mmH2O or higher and a moisture permeability of 1,000 g/m2/24 h or higher and (B) a microporous film.

  • Patent number: 6642047
    Abstract: The present invention provides a method and device for creating an environment in a container that is suitable for growing anaerobic bacteria. The device utilizes exothermic chemistry to deplete oxygen and drive the decomposition of a bicarbonate present in the closed system. The decomposition of the bicarbonate results in the release of carbon dioxide. The result of this exothermic reaction and decomposition of the bicarbonate in the closed system results in a suitable oxygen depleted, carbon dioxide enriched atmospheric environment for the growth of anaerobic bacteria. The device is formed of an air permeable package containing a heat generating composition and a bicarbonate. The air-permeable package is contained within an outer wrap that forms an air barrier to the air-permeable package. To activate the heat generating composition, the outer wrap is removed to expose the air-permeable package to the oxygen within the container.
