Abstract: The invention is an improved palladium-containing catalyst and process for preparing the catalyst. The catalyst is prepared by impregnating a dry activated carbon with a pH above 8 with a solution of palladium salt, separating the aqueous phase from the impregnated activated carbon when the aqueous phase has reached a pH of at least 1 and reducing the palladium which is supported on the activated carbon.

Abstract: A process for the production of catalyst materials stabilized in the active state, comprising activating the catalyst starting materials in a reducing gas atmosphere, impregnating the activated catalysts with the melt of a solid inert to the active catlayst, and solidifying the melt impregnation by cooling. The particulate catalyst starting material is passed under the reaction conditions of the activation stage through a reaction zone filled with the reducing gas atmosphere which is in direct contact with the melt of the impregnating solid; the activated catalyst material is introduced into this melt; subsequently removed therefrom; and the molten solid left to solidify. If desired, the impregnated catalyst material may be mechanically size-reduced.
