ABSTRACT:
Catalyst compositions are provided comprising a refractory support, about 0.1 to about 2 percent by weight of platinum, about 0.1 to about 2 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 said support. The relative weight ratio of the particles containing platinum and those containing iridium is between about 10:1 to 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. There is also disclosed a reforming process conducted in the presence of hydrogen, under reforming conditions, in the presence of the above catalyst.
