| abstract |
A hydrocarbon feedstock is catalytically reformed in a process which comprises at least three catalyst zones. The feedstock contacts a catalyst comprising platinum, a halogen, and a metal promoter on a solid catalyst support in a first catalyst zone. Effluent from the first catalyst zone contacts a catalyst comprising platinum, germanium and halogen on a solid catalyst support in an intermediate catalyst zone to obtain an intermediate effluent, which contacts a catalyst having the essential absence of germanium and comprising platinum, halogen and a metal promoter on a solid catalyst support in a terminal catalyst zone to obtain a reformate. |
