C6 RECYCLE FOR PROPYLENE GENERATION IN A FLUID CATALYTIC CRACKING UNIT |
摘要 |
The present invention relates to a process for selectively producing C3olefins from a catalytically cracked or thermally cracked naphtha stream. The process is practiced by recycling a C6 rich fraction of the catalytic naphtha product to the riser upstream the feed injection point, to a parallel riser, to the spent catalyst stripper, and/or to the reactor dilute phase immediately above the stripper.
