  • Publication number: 20090071876
    Abstract: A desulfurizing agent is produced by mixing a copper compound, a zinc compound and an ammonium compound with an aqueous solution of an alkali substance to prepare or precipitate followed by calcitrating the resulting precipitate to form a calcined precipitate into a shape form of a copper oxide-zinc oxide-aluminum oxide mixture. The shaped form is impregnated with iron or nickel and calcined to produce a calcined oxide and reduced with hydrogen to form a sulfur-absorption desulfurizing agent.

  • Publication number: 20080263953
    Abstract: The invention provides a method for operating a reformed gas production apparatus with which it is possible to achieve a high reforming efficiency while preventing a drop in catalyst activity due to the deposition of carbon. The reformed gas production method uses a reforming catalyst to reform a fuel that contains a hydrocarbon having at least two carbon atoms to produce a reformed gas that includes methane, hydrogen, and carbon monoxide. With this method, a fluid that includes the fuel, at least one of steam and a carbon dioxide-containing gas, and an oxygen-containing gas, is supplied to a reforming reaction region, and with the thermal decomposition index temperature of the fuel, which is determined by the type and the concentration of the hydrocarbons having at least two carbon atoms that make up the fuel, serving as an upper limit temperature of the reforming reaction region, the fluid is brought into contact with the reforming catalyst to produce the reformed gas.

  • Publication number: 20070229346
    Abstract: This invention provides a rubber composition and an electromagnetic wave absorbing sheet that can realize excellent electromagnetic wave absorbance properties while only having a small thickness and is also excellent in flexibility. The rubber composition comprises 100 parts by weight of a rubber component such as natural rubber and 300 to 1500 parts by weight, preferably 500 to 1000 parts by weight, of carbonyl iron. The incorporation of a predetermined amount of carbonyl iron in the rubber component can realize excellent electromagnetic wave absorbance properties, whereby the thickness of the electromagnetic wave absorbing sheet for providing a necessary electromagnetic wave absorbance amount can be reduced. The rubber composition comprising carbonyl iron incorporated together with the rubber component has low hardness, and is also excellent in flexibility. Accordingly, the rubber composition has good processability, is less likely to break, and is also excellent in durability.
