  • Publication number: 20140256541
    Abstract: A method for producing a dehydrogenation catalyst including an immersion step of impregnating an alumina layer of an alumina carrier with a platinum solution containing hexahydroxo platinate (IV) ions with an immersion method, wherein the alumina carrier has the alumina layer formed by anodic oxidation on at least a part of the surface of an aluminum support; and a calcination step of calcining the alumina carrier subjected to the immersion step to provide a dehydrogenation catalyst.
    Type: Application

  • Patent number: 8043989
    Abstract: A system is provided for desulfurizing a hydrocarbon fuel containing a light amount of methanol and a slight amount of water. The desulfurization system uses a Y-type zeolite-based desulfurizing agent containing at least copper arranged upstream of the system and an X-type zeolite-based desulfurizing agent containing at least silver arranged downstream of the system and thus can maintain desulfurization effect for a long period of time.

  • Publication number: 20100068572
    Abstract: A desulfurization agent for kerosene is provided that can remove efficiently the sulfurs contained in kerosene under low pressure conditions and thus is excellent in an effect to inhibit carbon deposition. The desulfurization agent contains 45 to 75 percent by mass of nickel oxide, 3 to 40 percent by mass of zinc oxide, 10 to 25 percent by mass of silica, 5 percent by mass or less of alumina and 0.1 percent by mass or less of sodium and has a BET specific surface area of 200 m2/g or greater.
