ABSTRACT:
Tin modified platinum-iridium catalysts provide high yields of C.sub.5 +liquid reformate in catalytic reforming, concurrent with high activity. In particular, the tin modified platinum-iridium catalysts are of unusually high selectivity, as contrasted with known iridium promoted platinum catalysts. The high selectivity is manifested in reforming a naphtha feed in a reactor charged to capacity with the catalyst, but particularly when used in the dehydrocyclization zone, or tail reactor of a series of reactors, while the lead reactors of the series contain a non tin-containing platinum catalyst, especially a platinum-iridium, or a platinum-rhenium catalyst. The tin modified platinum-iridium catalysts are also highly active, with only moderate loss in the high activity for which iridium stabilized platinum catalysts are known.
