ABSTRACT OF THE DISCLOSURE A naphtha reforming process wherein, in a series of catalyst-containing reforming zones, at least about 30 percent and preferably 50 percent to about 90 percent of the catalyst in the rearward most reforming zones is constituted of a platinum rhenium catalyst with a weight ratio of Pt:Re of at least 1.5:1, and the catalyst in the forwardmost reforming zone, is consti- tuted of platinum, or a platinum rhenium catalyst with a weight ratio of Pt:Re of less than 1.5:1. The naphtha- hydrogen contacting in the reforming zones is carried out at temperatures ranging from about 850°F to about 950°F (E.I.T.), at pressures ranging from about 150 psig to about 350 psig, and at gas rates ranging from about 2500 SCF/B to about 4500 SCF/B.
