Abstract: PROBLEM TO BE SOLVED: To produce a supported catalyst having higher catalytic activity than that of a known catalyst in the case of equal selectivity or improved selectivity. SOLUTION: In the case of the supported catalyst containing a mixture comprising palladium and/or its compound and an alkali metal compound, and additionally gold and/or its compound (system Pd/alkali metal/Au) or cadmium and/or its compound (system Pd/alkali metal/Cd) or barium and/or its compound (system Pd/alkali metal/Ba) or palladium, an alkali metal compound and gold and/or cadmium and/or barium, the catalyst on a carrier having a leakage passage is important, and an active component has an intrusion depth above 0.5-1.5 mm calculated from the surface area of a carrying material.

Abstract: Proceso para producir un catalizador de metal noble soportado, en el cual se ha aplicado al soporte clorurode paladio, que está envuelto por coloides de hidróxido/óxido de paladio y/o coloides de cloro-hidroxi-paladio,que se compone de los pasos siguientes: - hidrólisis de una solución acuosa de cloruro de paladio por la adición de una base fuerte a la solución decloruro de paladio a la temperatura ambiente mientras se mantiene un valor de pH inferior a 7, formando así unasuspensión coloidal, - precipitación de los coloides sobre el soporte por adición de la suspensión coloidal formada a una suspensiónacuosa de un soporte, - calentamiento de la suspensión resultante a 80ºC, - filtración en caliente la suspensión para producir el catalizador de metal noble soportado, y - lavado.

Abstract: The invention relates to a high performance catalyst containing a layer on an inert carrier body comprising noble metals from the platinum group deposited on support materials. The catalyst is characterised in that, the layer comprises platinum deposited in a washcoat consisting of A1203 which is stabilized with lanthana (La203), ceria (CeO2), which is stabilized with zirconia (ZrO2) and praseodymium (Pr6011). The supprot is promoted by sulfur-containing compounds which come from at least one of following compounds: platinum sulfite (PtSO3), sulfuric acid (H2SO4), ammonium sulfate ((NH4)2SO4), titanium oxysulfate (TiOSO4), titanium sulfate (Ti2(SO4)3), and zirconium sulfate (Zr(SO4)2).

Abstract: A supported catalyst comprising palladium and/or its compounds and alkali compounds, optionally with gold, barium and/or cadmium as the catalytically active components or a support (molded article) is characterized in that the catalyst is applied to a support having a through channel and the active components have a penetration depth of 0.5-1.5 mm measured from the surface of the support material. A supported catalyst (I) comprising palladium and/or its compounds and alkali compounds, as well as additionally gold and/or its compounds (system Pd/alkali/Au) or cadmium and/or its compounds (system Pd/alkali/Cd) or barium and/or its compounds (system Pd/alkali/Ba) or palladium, alkali compounds, and mixtures of gold and/or cadmium and/or barium as the catalytically active components or a support (molded article) is characterized in that the catalyst is applied to a support having a through channel and the active components have a penetration depth of 0.5-1.5 mm measured from the surface of the support material. Independent claims are included for: (i) a process for the production of the supported catalyst (I) by dipping, spraying, evaporating, soaking or precipitation of Pd-, Au-, Cd-, Ba-metal compounds, optionally reduction of the deposited metal compounds, optionally reduction of the deposited metal compounds, washing to remove chloride constituents and impregnation with alkali acetates or alkali compounds that are at least partially converted to alkali acetates under the reaction conditions for the production of vinyl acetate monomer; (ii) a molded article having a ring-like cylindrical state whose cross-section has a hollow cavity and having a free surface area of 1.6-77 % of the total surface area.
