Abstract:
A process for the catalytic reforming of a hydrocarbon feedstock which comprises contacting the feedstock with a catalyst having a particle diameter of between about 0.7 and about 3.5 mm and comprising a combination of a refractory inorganic oxide support with a multimetallic, multigradient metal component comprising about 0.01 to 2 mass-% on an elemental basis of a platinum-group-metal component, about 0.01 to 5 mass-% on an elemental basis of a homogeneously dispersed Group IVA (IUPAC 14) metal component and about 0.05 to 5 mass-% on an elemental basis of a surface-layer cerium component at reforming conditions to obtain an aromatics-enriched product.
