  • Patent number: 7776784
    Abstract: A hydrodesulfurization catalyst used for hydrodesulfurization of catalytically cracked gasoline comprises a support composed mainly of alumina modified with an oxide of at least one metal selected from the group consisting of iron, chromium, cobalt, nickel, copper, zinc, yttrium, scandium and lanthanoid-based metals, with at least one metal selected from the group consisting of Group 6A and Group 8 metals loaded as an active metal on the support. Hydrogenation of olefins generated as by-products during hydrodesulfurization of the catalytically cracked gasoline fraction, as an important constituent base of gasoline, can be adequately inhibited to maintain the octane number, while sufficiently reducing the sulfur content of the hydrodesulfurized catalytically cracked gasoline fraction.

    Abstract: The present invention provides a catalyst having high activity and excellent stability, a process for preparation of the catalyst, a membrane electrode assembly, and a fuel cell. The catalyst of the present invention comprises an electronically conductive support and catalyst fine particles. The catalyst fine particles are supported on the support and are represented by the formula (1): PtuRuxGeyTz (1). In the formula, u, x, y and z mean 30 to 60 atm %, 20 to 50 atm %, 0.5 to 20 atm % and 0.5 to 40 atm %, respectively. When the element represented by T is Al, Si, Ni, W, Mo, V or C, the content of the T-element's atoms connected with oxygen bonds is not more than four times as large as that of the T-element's atoms connected with metal bonds on the basis of X-ray photoelectron spectrum (XPS) analysis.

  • Patent number: 7759284
    Abstract: This invention relates to an improved process for preparing silver catalysts useful for the vapor phase production of ethylene oxide from ethylene and oxygen. An inert support is impregnated with a solution of a catalytically effective amount of a silver containing compound, a promoting amount of an alkali metal containing compound, and a promoting amount of a transition metal containing compound. The impregnated support is calcined by heating at a temperature of from about 200° C. to about 600° C. to convert the silver in the silver containing compound to metallic silver and to decompose and remove substantially all organic materials. The heating is conducted under an atmosphere comprising a combination of an inert gas and from about 10 ppm to about 5% by volume of a gas of an oxygen containing oxidizing component.
