Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a tin or lead component, a lanthanide series component, and a halogen component with a porous carrier material. The platinum group component, tin, or lead 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 % platinum group metal, about 0.01 to about 5 wt % tin or lead, and about 0.1 to about 3.5 wt % halogen. The lanthanide series component is present in amounts corresponding to an atomic ratio of lanthanide series component to platinum group metal of about 0.1:1 to about 1.25:1. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group metal is present therein in the elemental metallic state, while substantially all of the tin or lead component and of the lanthanide series component are present therein in oxidation states above that of the corresponding metal. A specific example of the type of hydrocarbon conversion process disclosed in a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the novel acidic multimetallic catalyst disclosed herein reforming conditions.
