    摘要： Compositions comprising iridium and at least one additional metal, preferably platinum, are disclosed in which the iridium and the additional metal or metals are present on a refractory support as highly dispersed polymetallic clusters. The metallic atoms in a cluster are separated by distances of about 2.5 to 4.0A. The degree of coverage of the surface of said refractory support by said polymetallic clusters is lower than about 10% and frequently lower than about 1%. The compositions are useful as hydrocarbon conversion catalysts, and iridiumplatinum catalysts containing a halogen moiety are especially useful for promoting naphtha reforming reactions.

    摘要： Supported coprecipitated nickel-cobalt-silica and nickel-cobalt-copper-silica hydrogenation catalysts are disclosed. The catalysts are prepared by preparing an aqueous reaction mixture containing nickel and cobalt cations (and optionally copper cations), silicate anions and solid porous carrier particles under agitation to form a coprecipitate of the nickel, cobalt (and optionally copper) and silicate ions onto said solid porous support particles; heating the aqueous reaction mixture; and adding an alkaline precipitating agent to further precipitate the nickel, cobalt (and optionally copper) and silicate anions onto said solid porous carrier particles.

    摘要： The instant invention pertains to a process for activating a reducing catalyst comprising the steps: (a) reducing said catalyst by heating the catalyst in the presence of hydrogen at a temperature sufficient to partially active catalyst; (b) contacting said partially active catalyst in the presence of hydrogen with a reactant feed which undergoes an exothermic reaction in the presence of said partially activated catalyst at conditions whereby said reaction occurs, said conditions including a temperature at least greater than the temperature at which the catalyst is partially activated; and (c) continuing said contacting for a time sufficient to convert said partially activated catalyst to a high activity catalyst. The catalyst is preferably a massive nickel catalyst comprised of nickel and silica, and more preferably comprised of nickel, copper and silica, and capable of having a reduced nickel surface area ranging from 55 to 100 m.sup.2 /g and a B.E.T. total surface area ranging from 150 to 300 m.sup.2 /g.

    摘要： Supported iridium-containing hydrocarbon conversion catalysts which are at least partially deactivated due to the deposition of carbonaceous residues thereon during contact with hydrocarbons are regenerated by contacting the catalyst, prior to contact with oxygen at elevated temperature, with a chlorine-containing reagent to increase the catalyst chlorine content to at least 1.0 wt. %, based on anhydrous catalyst, and thereafter contacting the catalyst with a gaseous mixture containing oxygen, a chlorine containing reagent, and water at a temperature of about 750.degree. to 1000.degree.F. for a time sufficient to burn at least a portion of the carbonaceous residues from the catalyst.
