Abstract
Abstract A novel 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 europium 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.
