MULTIZONE CATALYTIC REFORMING PROCESS WITH A PLURALITY OF CATALYSTS

摘要

A hydrocarbon feedstock is catalytically reformed in a process which comprises contacting the feedstock and hydrogen at catalytic reforming conditions in an initial catalyst zone with a catalyst comprising platinum, germanium and halogen on a solid catalyst support. The product stream and hydrogen from the first catalyst zone is thereafter contacted at catalytic reforming conditions in a terminal catalyst zone with catalyst A or B where catalyst A is essentially free of germanium and comprising platinum, germanium, halogen and a metal promoter on a solid catalyst support and where catalyst B comprises platinum, germanium, halogen and a metal promoter on a solid catalyst support.
