PROCESS FOR SELECTIVELY PRODUCING LIGHT OLEFINS IN A FLUID CATALYTIC CRACKING PROCESS |
| 摘要 |
A process for selectively producing C2-C4 olefins from a catalytically crack ed 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 conditio ns which include temperatures from about 500 to 650 ~C and a hydrocarbon partia l pressure from about 10 to 40 psia.
