Oyekau, S O; Swan, G A

A process wherein, in a series of reforming zones, or reactors, each of which contains a bed, or beds of catalyst, the catalyst in the leading reforming zones is constituted of supported platinum and a relatively low concentration of rhenium, and the catalyst in the last reforming zone, or reactor of the series, is constituted of platinum and a relatively high concentration of rhenium. The amount of rhenium relative to the platinum in the last reforming zone, or reactor is present in an atomic or weight ratio of rhenium:platinum of at least about 1.5:1; preferably at least about 2:1, and more preferably ranges from about 2:1 to about 3:1. The beds of catalyst are contacted with a hydrocarbon or naphtha feed and hydrogen at reforming conditions to produce a hydrocarbon, or naphtha product of improved octane, and the product is withdrawn.
