Continuous catalytic reforming process with dual zones

Abstract

A hydrocarbon feedstock is catalytically reformed in a sequence comprising a continuous-reforming zone, consisting essentially of a moving-bed catalytic reforming zone and continuous regeneration of catalyst particles, and a zeolitic-reforming zone containing a catalyst comprising a platinum-group metal and a nonacidic zeolite. The process combination permits higher severity, higher aromatics yields and/or increased throughput in the continuous-reforming zone, thus showing surprising benefits over prior-art processes, and is particularly useful in upgrading existing moving-bed reforming facilities with continuous catalyst regeneration.
