Process for preparing a supported Catalyst, Palladium, Gold and copper, Where The Catalyst is prepared by impregnating a porous Carrier with an aqueous solution of a water-soluble Salt of palladium and Copper.Setting the palladium and copper, and then The Catalyst impregnated with a water-soluble Salt of Gold (Divisional Application 1210 - 98).

摘要

Process for preparing a catalyst supported Palladium Gold and CopperWith a minor reduction in the amount of Copper In The Catalyst due to sublimation that when there is a Copper compound in the load,Comprising impregnating a porous Carrier with an aqueous solution of a water-soluble Salt of palladium and Copper.Setting the palladium and Copper in the form of non soluble compounds by the reaction of an Alkaline Compound, appropriateThen The Catalyst impregnated with a solution of a soluble Salt of the quantities of Gold and PalladiumIncluded in the elemental copper and Gold Impregnation Solutions equal to the Predetermined amounts of Palladium, copper and gold in the desired metal CatalystIn the setting of gold catalyst impregnating Solution present in the final by reacting soluble Salt dissolved in the solution with an Alkaline Compound suitable forPrecipitate a water-soluble Gold Compound, and the reduced form of the metal free compounds not water-soluble Palladium, copper and Gold are present in The Catalyst.
