摘要：
A process for producing propylene from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. 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 650° C. and a hydrocarbon partial pressure from about 10 to 40 psia. A separate stream containing aromatics may be co-fed with the naphtha stream.
