Abstract
Highly active catalysts, suitable for use in hydrogenation and other reactions, are prepared from an alloy of one or more of the Group VIII transition metals with a Group IIA metal, a Group IVB metal, or an actinide. The alloy is ground to the desired particle size and is thereafter reacted with a gas, such as carbon monoxide and hydrogen, to form an intimate physical admixture of the Group VIII metal or its corresponding carbide with the oxide of other metal.
Claims5
A method of preparing a catalyst which consists essentially of:
- providing an alloy of nickel and at least one further metal selected from the group consisting of zirconium, hafnium, calcium and uranium;
- reacting said alloy with a gas comprising H.sub.2 and CO at a temperature of about 300.degree. to 600.degree. C. for a time sufficiently long to oxidize said further metal to produce a catalyst consisting essentially of said nickel and an oxide of said further metal.
