    Abstract: The invention relates to a moulded, activated fixed-bed Raney metal catalyst. The catalyst is obtained by moulding a powder of at least one catalyst alloy with a power of the pure catalyst metals with the addition of moulding aids and pore-forming materials and subsequent calcination at temperatures below 850 DEG C. During the calcination, the moulding aids and pore-forming materials burn. Alloy powder and metal powder sinter together in the course of this to give a mechanically stable and porous moulding. This moulding thus comprises the particles of the catalyst alloys which are bound by powder of the pure catalyst metals. It does not contain any catalytically inactive ceramic or vitreous binders. By leaching out the aluminium contained in the catalyst alloys using sodium hydroxide solution, the moulding is activated in a surface shell.

    Abstract: The invention relates to a process for the uniform and reproducible shell impregnation of fixed-bed catalyst supports present as bulk material by application of impregnation solutions, divided into droplets, of catalytically active components to the catalyst supports circulated in a tank. By appropriate choice of the spray parameters, in particular of the drop-size spectrum, the amount of solvent and the amount of impregnation solution sprayed per tank revolution, the catalyst supports can be furnished with outstandingly uniform shells.
