A PROCESS FOR THE HYDROCONVERSION OF A HYDROCARBON LIQUID WHICH COMPRISES PASSING SAID LIQUID UNDER CONDITIONS OF HIGHLY TURBULENT FLOW THROUGH A FIRST ELONGATED REACTION ZONE AT A TEMPERATURE BETWEEN 700*F. AND 1400*F. AND A PRESSURE OF AT LEAST 500 P.S.I.G. IN THE PRESENCE OF ADDED HYDROGEN, PASSING AT LEAST A PORTION OF THE EFFLUENT FROM SAID FIRST REACTION ZONE INTO CONTACT WITH A HYDROGENATION CATALYST UNDER HYDROGENATION CONDITIONS INCLUDING A TEMPERATURE BETWEEN 600*F. AND 950*F., A PRESSURE BETWEEN ABOUT 500 AND 2,000 P.S.I.G. AND AT A SPACE VELOCITY BETWEEN 0.1 AND 10 LIQUID VOLUMES OF HYDROCARBON PER HOUR PER VOLUME OF CATALYST, PASSING AT LEAST A PORTION OF THE HYDROCARBON EFFLUENT FROM THE CATALYTIC ZONE IN THE PRESENCE OF HYDROGEN UNDER CONDITIONS OF HIGHLY TURBULENT FLOW THROUGH A SECOND ELONGATED REACTION ZONE AT A TEMPERATURE BETWEEN 800*F. AND 1500* F. AND A PRESSURE OF AT LEAST 500 P.S.I.G. AND RECOVERING THE PRODUCTS OF HYDROCONVERSION FROM THE EFFLUENT FROM SAID SECOND ELONGATED REACTION ZONE.
