Raney nickel catalysts from mechanical Ni-Al alloys

The catalytic properties of nickel Raney (NiR) catalysts may be influenced by the phase composition of the precursors—mechanically alloyed (MA) nickel aluminides. MA nickel aluminides can react with KOH solution and form NiR in the composition ratio Ni: Al= 1:1 while for melt and cast (MC) nickel al...

Zusammenfassung:	The catalytic properties of nickel Raney (NiR) catalysts may be influenced by the phase composition of the precursors—mechanically alloyed (MA) nickel aluminides. MA nickel aluminides can react with KOH solution and form NiR in the composition ratio Ni: Al= 1:1 while for melt and cast (MC) nickel aluminides this ratio never exceeds 2:3. NiR catalyst made from MA alloys contains Ni 3Al, in contrast to that made from melt and cast alloys.
