Method for producing supported Raney nickel catalyst

A method for making a supported Raney nickel catalyst by coating a nickel substrate with aluminum or aluminum-nickel alloy, heat treating the coated substrate above the melting point of aluminum but below 1133 DEG C, quenching at a temperature below 854 DEG C to form NiAl3 as a solid phase in the su...

Beschreibung
Zusammenfassung:	A method for making a supported Raney nickel catalyst by coating a nickel substrate with aluminum or aluminum-nickel alloy, heat treating the coated substrate above the melting point of aluminum but below 1133 DEG C, quenching at a temperature below 854 DEG C to form NiAl3 as a solid phase in the substrate. The Raney nickel alloy coating is activated in the usual manner by leaching with sodium hydroxide solution.
