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 yttrium or a rare earth metal. The alloy is ground to the desired particle size and is thereafter reacted with a gas containing carbon monoxide and hydrogen to form an intimate physical admixture of the Group VIII metal or its corresponding carbide with the oxide of yttrium or the rare earth metal.
Claims11
A method for preparing a catalyst which comprises:
- a. forming an alloy of a first metal selected from the group consisting of nickel, cobalt, iron and mixtures thereof with a second metal selected from the group consisting of yttrium, the rare earth metals and mixtures thereof, said first metal comprising from 5 to 95 wt-pct of said alloy;
- and
- b. reacting said alloy with a gas comprising hydrogen and carbon monoxide at a temperature sufficiently high for a time sufficiently long to oxidize said second metal.
