Abstract
A process for producing a product stream consisting primarily of the lower olefins ethylene, propylene and butylenes, and of gasoline is provided. The process includes cracking a mixture of paraffinic naphtha feedstream and regenerated catalyst in a downflow reactor. The reaction product stream is separated from the spent catalyst and subsequently fractionated into individual product streams, while the spent catalyst is regenerated and recycled.
