Claims19
A Raney iron catalyst comprising iron, cobalt, a third metal wherein the third metal is selected from the group consisting of nickel, rhodium, ruthenium, palladium, platinum, osmium, and iridium or a combination of any of these metals and wherein the concentration of the iron in the catalyst on a dry basis is at least 30% but not more than about 70% by weight;
- the concentration of the cobalt in the catalyst on a dry basis is from at least 10 to 40% by weight;
- the content of the third metal in the catalyst on a dry basis is from about 1 to not more than 6% by weight.
A Raney iron catalyst comprising iron, cobalt, and nickel, wherein the concentration of the iron in the catalyst on a dry basis is at least 30% but not more than about 70% by weight;
- the concentration of the cobalt in the catalyst on a dry basis is from at least 10 to 40% by weight;
- and the content of the nickel in the catalyst on a dry basis is from about 1 to not more than 6% by weight.
A Raney metal catalyst prepared by treating an alloy of metals with alkali, the alloy comprising from 20 to 50% by weight iron, 3 to 30% by weight cobalt, 0.5 to 3% by weight of a third metal wherein this third metal is selected from the group consisting of nickel, rhodium, ruthenium, palladium, platinum, osmium, iridium and mixtures of any of these metals and wherein the remainder of the mixture is an alkali soluble metal selected from the group consisting of aluminum, zinc, magnesium and silicon.
