摘要：
An improved catalyst particle is disclosed for the conversion of hydrocarbons which comprises a refractory inorganic-oxide support, a Friedel-Crafts metal halide, and a surface-layer platinum-group metal component, wherein the concentration of platinum-group metal component on the surface layer of each catalyst particle is at least 1.5 times the concentration in the central core of the catalyst particle. An isomerization process also is disclosed which is particularly effective for the conversion of C.sub.4 -C.sub.7 alkanes.
