The process comprises contacting a heavy hydrocarbon stream under suitable conditions and in the presence of hydrogen with a catalyst comprising a hydrogenating component selected from the group consisting of (1) molybdenum, chromium, and a small amount of cobalt, (2) their oxides, (3) their sulfides, and (4) mixtures thereof deposed on a large-pore, catalytically active alumina. The molybdenum is present in an amount within the range of about 5 wt.% to about 15 wt.%, calculated as MoO3 and based upon total catalyst weight, the chromium is present in an amount within the range of about 5 wt.% to about 20 wt.%, calculated as Cr2O3 and based upon the total catalyst weight, and the cobalt is present in an amount within the range of about 0.1 wt.% to about 5 wt.%, calculated as CoO and based upon the total catalyst weight. The catalyst possesses a pore volume within the range of about 0.4 cc/gm to about 0.8 cc/gm, a surface area within the range of about 150 m2/gm to about 300 m2/gm, and an average pore diameter within the range of about 100 A to about 200 A.
