Process for selectively producing light olefins in a fluid catalyst cracking process from a naphtha/steam feed
A process for selectively producing C2-C4 olefins from a catalytically cracked or thermally cracked naphtha stream is disclosed. A mixture of the naphtha stream and a stream of steam is feed into a reaction zone where it is contacted with a catalyst containing from about 10 to 50 wt. % of a crystall...

| description | A process for selectively producing C2-C4 olefins from a catalytically cracked or thermally cracked naphtha stream is disclosed. A mixture of the naphtha stream and a stream of steam is feed into a reaction zone where it 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 to 650 DEG C. and a hydrocarbon partial pressure from about 10 to 40 psia. |
