Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
68 words
The method of claim 1 wherein a mixture of a trioxide of a Group VI-B metal and an amount of platinum, palladium, or thier oxides in the rAnge of about 0.5 to about 2 weight percent of the total mixture is exposed to water vapor and hydrogen at an activation temperature of less than 100*C for a time sufficient to produce the catalyst comprising a hydrogen metal bronze.
Claim 2
Dependent Claim
10 words
The method of claim 1 wherein the metal is tungsten.
Claim 3
Dependent Claim
10 words
The method of claim 1 wherein the metal is molybdenum.
Claim 4
Dependent Claim
23 words
The method of claim 1 wherein the reaction temperature is in the range of 250* to 350* C whereby isomerization reaction is favored.
Claim 5
Dependent Claim
23 words
