Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic substantially sulfur-free multimetallic catalytic composite comprising a combination of catalytically effective and available amounts of a platinum group metal, cadmium, cobalt, and halogen with a porous carrier material. The platinum group, cadmium, cobalt, and halogen components are present in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt % platinum group metal, about 0.01 to about 5 wt % cadmium, about 0.05 to about 5 wt % cobalt, and about 0.1 to about 3.5 wt % halogen. These metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group component is present therein in the elemental metallic state, substantially all of the catalytically available cobalt component 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, while substantially all of the cadmium component is preferably present therein in an oxidation state above that of the elemental metal.
