Abstract
Abstract A hydrotreating (or hydrorefining) catalyst of an aluminacontaining porous carrier material, a nickel component and a phosphorous component. The catalyst contains from about 1.0 to about 10.0 percent by weight of a nickel component and from about 5.0 to about 40.0 percent by weight of a phosphorous component; preferred catalysts also contain from 4.0 to about 30.0 percent by weight of a Group VI-B metal component. The catalyst is prepared in a manner which inhibits the formation of nickel aluminate to the extent that not more than 0.1 percent by weight thereof is present in the final catalytic composite.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
17 words
The catalyst of claim 1 further characterized in that a Group VI-B metal component is combined therewith.
Claim 2
Dependent Claim
16 words
The catalyst of claim 1 further characterized in that said carrier material is a crystalline aluminosilicate.
Claim 3
Dependent Claim
123 words
A hydrotreating catalyst comprising coextruded particles of a carrier material selected from the group consisting of alumina and alumina-silica, from about 4.0 percent to about 30.0 percent by weight of a Group VI-B metal component, from about 1.0 percent to about 10.0 percent by weight of a nickel component and from about 5.0 percent to about 40.0 percent by weight of a phosphorous component, and containing less than 0.1 percent by weight of nickel aluminate, said catalyst having been prepared by mixing a preformed carrier material as specified above with Group VI-B metal and nickel components and phosphoric acid, extruding the resulting mixture, drying and calcining the resulting extrudate, said phosphoric acid functioning to minimize formation of nickel aluminate during said calcination step.
Claim 4
Dependent Claim
21 words
The catalyst of claim 4 further characterized in that said Group VI-B metal component is molybdenum, or a compound of molybdenum.
Claim 5
Dependent Claim
21 words
The catalyst of claim 4 further characterized in that said Group VI-B metal component is tungsten, or a compound of tungsten.
Claim 6
Dependent Claim
120 words
A process for desulfurizing a sulfurous hydrocarbon charge stock which comprises reacting said charge stock and hydrogen, at desulfurization conditions, selected to convert sulfurous compounds into hydrogen sulfide and hydrocarbons, in contact with a coextruded composite of a carrier material selected from the group consisting of alumina and alumina-silica, a nickel component, a Group VI-B metal component and a phosphorous component, and containing less than 0.1 percent by weight of nickel aluminate, said catalyst having been prepared by mixing a preformed carrier material as specified above with Group VI-B metal and nickel components and phosphoric acid, extruding the resulting mixture, drying and calcining the resulting extrudate, said phosphoric acid functioning to minimize formation of nickel aluminate during said calcination step.
