Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 48 words
An essentially unsupported nickel catalyst which comprises nickel as the main ingredient, from about 30 to 40% by weight of copper, based on nickel, and from about 1 to 10% by weight of a mixture of manganese and molybdenum oxides, based on the total weight of the catalyst.
Claim 2
Dependent Claim 48 words
An essentially unsupported nickel catalyst which comprises nickel as the main ingredient, from about 30 to 40% by weight of copper, based on nickel, and from about 1 to 10% by weight of a mixture of manganese and molybdenum oxides, based on the total weight of the catalyst.
Claim 3
Dependent Claim 22 words
A catalyst as set forth in claim 1, wherein the ratio of manganese oxide to molybdenum oxide is from 1:10 to 10:1.
Claim 4
Dependent Claim 69 words
A catalyst as set forth in claim 1, which is obtained by subjecting a mixture of from about 50 to 80% by weight of nickel oxide, from 15 to 35% by weight of copper oxide, from 0.3 to 6% by weight of manganese oxide and from 0.1 to 5% by weight of molybdenum oxide in a shape suitable for use as a fixed catalyst bed to reduction with hydrogen.
Claim 5
Dependent Claim 44 words
A catalyst as set forth in claim 1 wherein said catalyst is in the form of pellets or tablets and wherein said catalyst is designed for the hydrogenation of acetylene alcohols to the corresponding saturated alcohols in liquid phase in a fixed catalyst bed.
