The hydrocarbons are converted by contacting them at conversion conditions with an acidic sulfur-free multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a rhenium component, a cobalt component, and a halogen component with a porous carrier material. The platinum group component, rhenium component, cobalt component, and halogen component are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. percent platinum group metal, about 0.01 to about 2 wt. percent rhenium, about 0.1 to about 5 wt. percent cobalt, and about 0.1 to about 3.5 wt. percent halogen. Moreover, the catalytically active sites induced by these metallic components are uniformly dispersed throughout the porous carrier material and these components are present in the catalyst in carefully controlled oxidation states such that substantially all of the platinum group component is in the elemental metallic state, substantially all of the rhenium and catalytically available cobalt components are 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. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the acidic sulfur-free multimetallic at reforming conditions. 26 claims.
