PROCESS FOR SELECTIVELY PRODUCING C3 OLEFINS IN A FLUID CATALYTIC CRACKING PROCESS
Application IN/PCT/2000/00526/MUM published 2007-01-19, filed 2000-10-20
A process for selectively producing olefins containing 3 carbons from a catalytically cracked or thermally cracked naphtha stream. The process involves reacting the cracked naphtha in the presence of a catalyst containing from about 10 to 50 wt.% of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers, stripping the catalyst, regenerating the catalyst and fractionating the reaction products. Process conditions include temperatures ranging from about 500-650 degrees celsius and a hydrocarbon partial pressure from about 10 to 40 psia.
