Abstract
A process for reforming a naphtha feed at reforming conditions by contacting said feed, and hydrogen, with a halogenated, supported platinum-rhenium catalyst promoted with an agglomerated iridium component. The iridium component is agglomerated sufficient to exhibit a crystallinity greater than 50 percent, preferably greater than 75 percent, and more preferably 100 percent, as measured by X-ray.

In a process for catalytically reforming, with hydrogen, a hydrocarbon naphtha feed at reforming conditions, the improvement comprising contacting said naphtha feed, and hydrogen, with a halogenated, supported platinum-rhenium catalyst promoted with iridium agglomerated to exhibit a crystallinity greater than 50 percent, as measured by X-ray.
In a process for catalytically reforming, with hydrogen, a naphtha feed at reforming conditions by contacting said naphtha feed with a reforming catalyst which contains from about 0.05 percent to about 1 percent platinum, from about 0.05 percent to about 1 percent rhenium, from about 0.01 to about 1 percent iridium, from about 0.1 to about 2.5 percent halogen, and sulfur in concentrations ranging up to about 0.2 percent, the improvement wherein the iridium component of said catalyst is agglomerated to exhibit a crystallinity greater than 50 percent, as measured by X-ray.
