Abstract: 1. A PROCESS FOR THE CONVERSION OF A HEAVY HYDROCARBON OIL COMPRISING CONTACTING SAID OIL WITH HYDROGEN AND A CATALYST COMPOSITE COMPRISING A CATALYTIC METAL OR COMPOUND THEREOF ON A POROUS SILICA-ALUMINA CARRIER HAVING A SILICA CONTENT IN THE RANGE OF BETWEEN 0 AND ABOUT 30% BY WEIGHT AND FURTHER CHARACTERIZED IN THAT: (1) THE VOLUME OF THE PORES IN SAID CATALYST HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 3000 A. IS GREATER THAN ABOUT 0.30 ML./G.; (2) THE VOLUME OF THE PORES IN SAID CATALYST HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 30 A. IS LESS THAN ABOUT 25% OF THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 300 A.; (3) THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 75 TO ABOUT 3300 A. IS LESS THAN ABOUT 40% OF THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 0 TO ABOUT 300 A.; AND (4) THE VOLUME OF THE PORES HAVING A RADIUS IN THE RANGE OF FROM ABOUT 75 TO ABOUT 75,000 A. IS SMALLER THAN ABOUT 0.25 ML./G.
