ABSTRACT:
Catalyst compositions are provided consisting essentially of a refractory support about 0.1 to about 5 percent by weight of platinum, about 0.1 to about 5 percent by weight of iridium and about 0.1 to about 5 weight percent of halogen, where the platinum and iridium are contained on separate particles of support. The relative weight ratio of the particles containing platinum are those containing iridium is between about 10:1 and about 1:10. The compositions are useful as hydrocarbon conversion catalysts and are especially applicable for use in catalyzing the reforming of naphtha petroleum fractions.
