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.
