ABSTRACT:
A novel catalyst and the use thereof in a reforming process is disclosed. The dual-function catalyst comprises a refractory inorganic oxide, indium, Group IVA(IUPAC 14) metal, and a platinum-group metal concentrated in the surface layer of each catalyst particle. Utilization of this catalyst in the conversion of hydrocarbons, especially in reforming, results in significantly improved selectivity to the desired gasoline or aromatics product.
