A catalyst and the use thereof in a reforming process is disclosed. The catalyst comprises a refractory inorganic oxide, platinum-group metal, Group IVA(IUPAC 14) metal, and lanthanide-series metal in a specified ratio. Utilization of this catalyst in the reforming of hydrocarbons, especially in reforming, results in significantly improved selectivity to the desired gasoline or aromatics product.

[ I claim:] [1.]1. A catalytic composite consisting essentially of a combination of a refractory inorganic oxide support with about 0.1 to 10 mass % of a halogen component, about 0.01 to 5 mass % on an elemental basis of a Group IVA (IUPAC 14) metal component, about 0.01 to 2 mass % on an elemental basis of a platinum-group metal component, and about 0.05 to 5 mass % on an elemental basis of a lanthanide component comprising at least one lanthanide selected from the group consisting of ytterbium, europium and samarium wherein more than about 50% of the lanthanide is present as the +2 oxide.
