THE PROCESS OF CONVERTING HYDROCARBON OILS TO DESIRABLE COMPONENTS WHICH COMPRISES CONTACTING THE OIL IN THE PRESENCE OF HYDROGEN UNDER HYDROCARBON CONVERSION CONDITIONS INCLUDING A TEMPERATURE OF ABOUT 500 TO 1200*F., WITH A CATALYST CONSISTING ESSENTIALLY OF A CATALYTIC AMOUNT OF A METAL COMPONENT SELECTED FROM THE GROUP CONSISTING OF GROUP VIB AND GROUP VIII SUPPORTED ON GAMMA-ALUMINA OBTAINED BY THE DRYING AND CALCINING OF A BOEHMITE ALUMINA PRODUCT, GRANULAR IN APPERANCE WITH ACICULAR PARTICLES OF IRREGULAR EDGES, A PORE STRUCTURE TOTALLING AT LEAST ABOUT 0.5 CC. PER GRAM IN PORES LARGER THAN 80 A. IN SIZE, AN AVERAGE CRYSTALLITE SIZE GREATER THAN ABOUT 40 A. UP TO ABOUT 200 A. BY X-RAY DIFFRACTION ANALYSIS AND COMPOSED OF A NONHOMOGENEOUS INTEGRAL AGGREGATION OF POLYCRYSTALLINE BOEHMITE SUB-UNITS, SAID PARTICLES HAVING A LARGEST DIMENSION OF AT LEAST ABOUT 500 A.
