A SELECTED PRODUCT DISTRIBUTION, SUCH AS BETWEEN GASOLINE AND LIGHT CYCLE GAS-OIL, IS MAINTAINED BY RECOVERING LIGHT CYCLE GAS-OIL AT A SELCTED RATE FROM THE PRODUCT FRACTIONATION ZONE, AND CONTROLLING HYDROCARBON CONVERSION IN THE REACTION ZONE TO MAINTAIN A SET RATE FOR A HEAVY CYCLE GASOIL RECYCLE STREAM. THE GASOLINE PRODUCT IS RECOVERED FROM THE PRODUCT FRACTIONATION ZONE AT THE RATE IT IS PRODUCED. PROCESS CONTROL MEANS FOR OPERATING THE PROCESS IN THE ABOVE MANNER ARE DISCLOSED.
