Abstract 1. A PROCESS FOR HYDRODESULFURIZING A FEED RESIDUAL OIL COMPRISING CONTACTING THE FEED OIL AND HYDROGEN WITH A HYDROSULFURIZATION CATALYST AT A TEMPERATURE OF ABOUT 600 TO ABOUT 1,000* F., A LIQUID HOURLY SPACE VELOCITY OF FROM ABOUT 0.1 TO ABOUT 10 VOLUMES OF FEED OIL PER VOLUME OF CATALYST PER HOUR AND A HYDROGEN FEED RATE OF FROM ABOUT 500 TO ABOUT 10,000 STANDARD CUBIC FEED OF HYDROGEN PER BARREL OF FEED OIL, SAID CATALYST COMPRISING A MINOR AMOUNT OF GROUP VI AND GROUP VIII METALS WITH A MAJOR AMOUNT OF AN ALUMINA CARRIER CONTAINING LESS THAN 1 WEIGHT PERCENT SILICA, SAID ALUMINA CARRIER COMPOSITED OF A FIRST ALUMINA OBTAINED BY DRYING AND CALCINING A CRYSTALLINE ALUMINA TRIHYDRATE AND A SECOND ALUMINA OBTAINED BY DRYING AND CALCINING A CRYSTALLINE ALUMINA HYDRATE CONTAINING FROM 1.2 TO 2.6 MOLS OF WATER OF HYDRATION PER MOL OF AL2O3, THE ALUMINA TRIHYDRATE COMPRISING AN AMOUNT FROM ABOUT 2 TO ABOUT 35 WEIGHT PERCENT OF THE TOTAL OF SAID HYDRATES WHICH INCREASES THE SPECIFIC HYDRODESULFURIZATION ACTIVITY OF SAID CATALYST.
