<p>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 °C to about 650 °C and a hydrocarbon partial pressure from about 10 to 40 psia. The resulting product is a high octane naphtha.</p> |
