Abstract

A process for increasing the yield of C3 and C4 olefins by injecting light cat naphtha and cat cycle oil together with steam into an upstream reaction zone of a FCC riser reactor. The products of the upstream reaction zone are conducted to a downstream reaction zone and combined with fresh feed in the downstream reaction zone.
