Abstract

A hydrocarbon feedstock is catalytically reformed in a process which comprises contacting the feedstock in an initial catalyst zone with a catalyst comprising platinum, germanium and halogen on a solid catalyst support. The product from the first catalyst zone is contacted in a terminal catalyst zone with a catalyst having the essential absence of germanium and comprising platinum, halogen and a metal promoter on a solid catalyst support.
