Process for the manufacture of Raney nickel catalysts, characterized in that the molten mixture of an alloy of 50 to 95% by weight of aluminum, 10 to 50% by weight of nickel, 0 to 20% by weight of iron, 0 to 15% by weight of cerium, cerium-metal mixture, vanadium, niobium, tantalum, chromium, molybdenum or manganese, as well as other vitrifying elements, it is cooled to a cooling rate> 10 4K / s by pressing the alloy melt in a rotating cooling wheel or in the groove between two cooling wheels that rotate in the opposite direction and then the solidified alloy quickly undergoes a treatment with organic or inorganic bases. |
