PROCESS FOR SELECTIVELY PRODUCING HIGH OCTANE NAPHTHA.

摘要

This invention is related to a catalytically cracked or thermally cracked naphtha stream. The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt.% of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures from about 500 deg;C to about 650 deg;C and a hydrocarbon partial pressure from about 10 to 40 psia. The resulting product is a high octane naphtha.
