Abstract
Abstract Asphaltene-containing hydrocarbonaceous black oils are hydrogenated in a slurry process utilizing a hydrogen transfer agent. The transfer agent constitutes a finely divided sponge metal, saturated with hydrogen at elevated pressure, and admixed with the charge stock to form a reactive slurry. Preferred sponge metals include titanium, zirconium, vanadium, tungsten and nickel. In a specific embodiment, the reactive slurry also contains a hydrorefining catalyst of an unsupported sulfide of a Group V-B metal.

Claim 2
Dependent Claim
14 words
The process of claim 1 further characterized in that said sponge metal is titanium.
Claim 3
Dependent Claim
14 words
The process of claim 1 further characterized in that said sponge metal is zirconium.
Claim 4
Dependent Claim
14 words
The process of claim 1 further characterized in that said sponge metal is vanadium.
Claim 5
Dependent Claim
14 words
The process of claim 1 further characterized in that said sponge metal is tungsten.
Claim 6
Dependent Claim
14 words
The process of claim 1 further characterized in that said sponge metal is nickel.
Claim 7
Dependent Claim
24 words
The process of claim 1 further characterized in that said slurry contains, as a hydrorefining catalyst, an unsupported sulfide of a Group V-B metal.
Claim 8
Dependent Claim
18 words
The process of claim 8 further characterized in that said Group V-B metal sulfide is a vanadium sulfide.
Claim 9
Dependent Claim
26 words
The process of claim 8 further characterized in that said slurry contains from 1.0 to about 25.0 percent by weight of said Group V-B metal sulfide.
Claim 10
Dependent Claim
82 words
A process for hydrorefining an asphaltene-containing hydrocarbonaceous charge stock which comprises saturating a finely divided sponge metal with hydrogen at a pressure greater than about 500 p.s.i.g. and a temperature in the range of about 175* to about 350* C., admixing with the charge stock said hydrogen-saturated sponge metal and a hydrorefining catalyst comprising an unsupported sulfide of a Group V-B metal, and reacting the resulting slurry at a pressure greater than about 500 p.s.i.g. and a temperature above about 350* C.
Claim 11
Dependent Claim
