Abstract
A process and apparatus is for recycling HCO and/or naphtha from a first FCC unit to a second FCC unit to recover additional distillate and/or light olefins. A first catalyst stream for the first FCC unit may be isolated from a second catalyst stream for the second FCC unit. Fractionation of second cracked products from the second FCC unit may be separate from fractionation of first cracked products from the first FCC unit.
