Abstract

Abstract A PROCESS FOR THE EFFICIENT HYDROCRACKING OF A HEAVY HYDROCARBON OIL SUCH AS VACUUMOR ATMOSPHERIC RESIDUUMS IS DISCLOSED HEREIN. THE HEAVY OIL IS CONTACTED WITH HYDROGEN IN THE PRESENCE OF A PARTICULATE CATALYST AT HIGH PRESSURES, PREFERABLY BETWEEN 1,50 AND ABOUT 3,000 P.S.I. AND HIGH TEMPERATURES, PREFERABLY BETWEEN 800*F. AND 850*F., BY PASSING THE HEAVY OIL AND A HYDROGEN CONTAINING GAS UPWARDLY THROUGH THE PARTICULATE CATALYST IN A FIRST REACTOR. EFFIUENT FROM THE FIRST REACTOR IS MIXED WITH A HYDROCARBON DILUENT AND PASSED UPWARDLY THROUGH A CATALYST BED IN A SECOND HIGH PRESSURE AND HIGH TEMPERATURE REACTOR MAINTAINED AT SIMILAR CONDITIONS TO THE FIRST REACTOR. OIL IS WITHDRAWN FROM THE SECOND REACTOR FOR FURTHER PROCESSING AS MAY BE DESIRED. PREFERABLY THE DILUENT IS A HYDROCARBON STREAM BOILING IN THE RANGE OF FROM 500* TO 975*F. AND MORE PREFERABLY 600*F, TO 800*F. AND IS MIXED WITH THE EFFLUENT FROM THE FIRST REACTOR IN THE AMOUNT OF FROM I0% TO 100% BY VOLUME OF THE VOLUME OF THE EFFUENT.
