Abstract
Abstract A catalyst composition prepared by depositing a metal or metal compound onto a carbon support formed, in effect, simultaneously with the deposition of the metal or metal compound via partial combustion of an unsaturated hydrocarbon and thereafter converting said metal or metal compound to an oxide or sulfide having hydrogenation activity. The metal is selected from the group of metals consisting of Groups II-B, IV-B, IV-A, V-A, VI-A, VII-A and VIII-A metals of the Periodic Table of the Elements. The catalyst compositions are useful in hydroconversion and hydrotreating processes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
116 words
A catalyst composition comprising at least one metal oxide or sulfide of a metal selected from the group of metals consisting of the Group II-B, IV-B, IV-A, V-A. VI-A, VII-A and VIII-A metals of the Periodic Table of the Elements and a carbon support, which carbon support is formed by combustion of an unsaturated hydrocarbon in an atmosphere containing less oxygen than that required for complete combustion of the unsaturated hydrocarbon, said metal having been vaporized, at least in part, with heat from a combustion of said unsaturated hydrocarbon and deposited onto the carbon support from the vapor phase, said metal oxide or sulfide having a maximum dimension in any direction up to about 150 Angstroms.
Claim 2
Dependent Claim
116 words
A catalyst composition comprising at least one metal oxide or sulfide of a metal selected from the group of metals consisting of the Group II-B, IV-B, IV-A, V-A. VI-A, VII-A and VIII-A metals of the Periodic Table of the Elements and a carbon support, which carbon support is formed by combustion of an unsaturated hydrocarbon in an atmosphere containing less oxygen than that required for complete combustion of the unsaturated hydrocarbon, said metal having been vaporized, at least in part, with heat from a combustion of said unsaturated hydrocarbon and deposited onto the carbon support from the vapor phase, said metal oxide or sulfide having a maximum dimension in any direction up to about 150 Angstroms.
