Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
84 words
A process for hydrorefining a hydrocarbon charge stock which comprises reacting an admixture of said charge stock with hydrogen and with non-stoichiometric vanadium sulfide catalyst which is prepared according to the following method: (a) contacting vanadium oxide with ammonium sulfide at a temperature and pressure sufficient to form an ammonium salt of the vanadium sulfide; (b) thermally decomposing the resulting ammonium salt of the vanadium sulfide derived from step (a) in a non-oxidative atmosphere; and (c) recovering said vanadium sulfide catalyst from step (b).
Claim 2
Dependent Claim
84 words
A process for hydrorefining a hydrocarbon charge stock which comprises reacting an admixture of said charge stock with hydrogen and with non-stoichiometric vanadium sulfide catalyst which is prepared according to the following method: (a) contacting vanadium oxide with ammonium sulfide at a temperature and pressure sufficient to form an ammonium salt of the vanadium sulfide; (b) thermally decomposing the resulting ammonium salt of the vanadium sulfide derived from step (a) in a non-oxidative atmosphere; and (c) recovering said vanadium sulfide catalyst from step (b).
Claim 3
Dependent Claim
13 words
The process of claim 1 wherein said hydrocarbon charge stock contains pentane-insoluble asphaltenes.
Claim 4
Dependent Claim
11 words
The process of claim 1 wherein said non-oxidative atmosphere comprises hydrogen.
Claim 5
Dependent Claim
11 words
The process of claim 1 wherein said non-oxidative atmosphere comprises nitrogen.
