Abstract
Abstract A non-stoichiometric vanadium sulfide catalyst utilized in a hydrocarbon hydrorefining process is prepared by contacting a sulfur-bearing gas, such as H 2 S, into an alkali metal hydroxide solution containing vanadium oxide to form a soluble alkali metal vanadium sulfide. The vanadium sulfide is precipitated from the soluble alkali metal vanadium sulfide with an acid, such as sulfuric acid or carbonic acid.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 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) dissolve a vanadium oxide in an alkali metal hydroxide solution; (b) contact the resulting vanadium solution from step (a) with a sulfur-bearing gas to form a soluble alkali metal vandium sulfide; (c) neutralize the resulting solution from step (b) with an acid to precipitate vanadium sulfide; (d) passing the resulting vanadium sulfide from step (c) to form said admixture of said hydrocarbon charge stock with hydrogen and with catalyst.
Claim 2
Dependent Claim
103 words
