Abstract:
1. A process for the production of Raney nickel catalysts, comprising (1) contacting (a) the melt of an alloy which comprises (i) from 40 to 95 wt. % aluminum, (ii) from 5 to 50 wt. % nickel, (iii) from 0 to 20 wt. % iron, (iv) from 0 to 15 wt. % of one or more transition metals selected from the group consisting of cerium, cerium mixed metal, vanadium, niobium, tantalum, chromium, molybdenum and manganese, and, (v) optionally, additional glass-forming elements; with (b) one or more rotating cooling rollers or cooling plates, wherein the surface of said cooling rollers is structured by means of transverse grooves and the surface of said cooling plates is structured by means of grooves which extend outwardly from the axis of rotation, (2) allowing the melt to cool and solidify on said rotating cooling rollers or cooling plates; and (3) treating the rapidly solidified alloy with one or more organic bases and/or inorganic bases.
