ABSTRACT:
A process for hydrotreating (hydroprocessing) hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite comprising a porous carrier material containing, on an elemental basis, about 0.01 to about 2 wt. % platinum or palladium, about 0.05 to about 5 wt. % cobalt, about 0.01 to about 2 wt. % rhodium and about 0.1 to about 3.5 wt. % halogen, wherein the platinum or palladium, cobalt and rhodium are uniformly dispersed throughout the porous carrier material, wherein substantially all of the platinum or palladium is present in the elemental metallic state, wherein substantially all of the rhodium is present in the elemental metal, and wherein substantially all of the catalytically available cobalt is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions or in a mixture of these states, in which process there is effected a chemical consumption of hydrogen. A preferred modifying component for the disclosed catalytic composite is a Group IVA metallic component. A specific example of one such catalyst is a composite of a crystalline aluminosilicate, a platinum component, a cobalt component, a rhodium component, and a halogen component, for utilization in a hydrocracking process. Other hydrocarbon hydroprocesses are directed toward the hydrogenation of aromatic nuclei, the ring-opening of cyclic hydrocarbons, hydrogenation, etc.
