Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
A substantially alkali-free, heat treated catalyst composition for the production of gases rich in hydrogen or methane with decreased carbon lay-down prepared by a method which comprises: supporting on a refractory material having a surface area of at least one square meter per gram and selected from oxides of aluminum, silicon, magnesium, calcium, titanium or mixtures thereof a. between about 5 and about 70 weight percent basis the total catalyst weight and calculated as the metal of a nickel compound selected from elemental nickel, a reducible compound of nickel or mixtures thereof; b. at least 0.5 weight percent basis the total catalyst weight and calculated as the metal of a cobalt compound selected from elemental cobalt, a reducible compound of cobalt or mixtures thereof; after support of the cobalt compound on the refractory, heat treating the catalyst composition under non-reducing conditions at a temperature of at most 1100°F.
Claim 2
Dependent Claim
148 words
A substantially alkali-free, heat treated catalyst composition for the production of gases rich in hydrogen or methane with decreased carbon lay-down prepared by a method which comprises: supporting on a refractory material having a surface area of at least one square meter per gram and selected from oxides of aluminum, silicon, magnesium, calcium, titanium or mixtures thereof a. between about 5 and about 70 weight percent basis the total catalyst weight and calculated as the metal of a nickel compound selected from elemental nickel, a reducible compound of nickel or mixtures thereof; b. at least 0.5 weight percent basis the total catalyst weight and calculated as the metal of a cobalt compound selected from elemental cobalt, a reducible compound of cobalt or mixtures thereof; after support of the cobalt compound on the refractory, heat treating the catalyst composition under non-reducing conditions at a temperature of at most 1100°F.
Claim 3
Dependent Claim
26 words

Claim 6
Dependent Claim
27 words
The catalyst composition of claim 1 in which the nickel content of the catalyst is between about 15 and about 60 weight percent calculated as the metal.
