Abstract: A process and apparatus for recycling LCO and/or HCO to a hydroprocessing zone to saturate aromatics for cracking in an FCC unit is disclosed. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone that is primarily for demetallizing (and desulfurizing) feed to the FCC unit.
