Abstract
Abstract A hydrorefining process is disclosed. A petroleum hydrocarbon fraction is treated at hydrorefining conditions in contact with a catalyst comprising a Group VIII metal and a Group VIB metal component impregnated on a refractory inorganic oxide. A more active catalyst results from the use of an impregnating solution comprising an anionic complex of a Group VIB and a Group VIII metal.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
133 words
A hydrorefining process which comprises treating a petroleum hydrocarbon fraction at hydrorefining conditions to reduce the sulfur content of said fraction; in contact with a catalyst comprising a refractory inorganic oxide impregnated with a Group VIB and a Group VIII metal component, said catalyst having been prepared by impregnating said refractory inorganic oxide with an aqueous solution comprising an anion complex of a Group VIB metal and a Group VIII metal sufficient to provide a catalyst containing from about 5 to about 20 wt. % Group VIB metal, and with a simple salt of a Group VIII metal sufficient in combination with said anionic complex to provide a catalyst containing from about 0.1 to about 10 wt. % Group VIII metal drying said impregnated inorganic oxide and calcining the dried impregnated inorganic oxide.
Claim 2
Dependent Claim
133 words
A hydrorefining process which comprises treating a petroleum hydrocarbon fraction at hydrorefining conditions to reduce the sulfur content of said fraction; in contact with a catalyst comprising a refractory inorganic oxide impregnated with a Group VIB and a Group VIII metal component, said catalyst having been prepared by impregnating said refractory inorganic oxide with an aqueous solution comprising an anion complex of a Group VIB metal and a Group VIII metal sufficient to provide a catalyst containing from about 5 to about 20 wt. % Group VIB metal, and with a simple salt of a Group VIII metal sufficient in combination with said anionic complex to provide a catalyst containing from about 0.1 to about 10 wt. % Group VIII metal drying said impregnated inorganic oxide and calcining the dried impregnated inorganic oxide.
