A process for hydrotreating a hydrocarbon feed containing components boiling above 1000.degree. F. and sulfur, metals and carbon residue utilizing a heterogeneous catalyst having a specified pore size distribution, median pore diameter by surface area and pore mode by volume, to give a product containing a decreased content of components boiling above 1000.degree. F. and decreased sulfur, metals and carbon residue is disclosed. The process includes contacting the hydrocarbon feed with hydrogen in the presence of the catalyst at isothermal hydroconversion conditions. The catalyst includes an porous alumina support containing less than or equal to 2.5 wt % silica on the finished catalyst basis, and bearing 2.2 to 6 wt % of a Group VIII metal oxide, 7 to 24 wt % of a Group VIB metal oxide and preferably less than 0.2 wt % of a phosphorous oxide. The catalyst may be characterized as having a Total Surface Area of 215 to 245 m.sup.2 /g, a Total Pore Volume of 0.82 to 0.98 cc/g, a Median Pore Diameter by Surface Area of 91 to 104 .ANG., and a Pore Diameter Distribution in which 22.0 to 33.0% of the total Pore Volume is present as macropores of a diameter greater than 250 .ANG., 67.0 to 78.0% of the Total Pore Volume is present as micropores of a diameter less that 250 .ANG.. Greater than or equal to 65% of the micropore volume is present as micropores having a diameter +/-25 .ANG. about a Pore Mode by volume of 86-99 .ANG.. Less than 0.08 cc/g of the micropore volume is present in micropores with diameters less than 80 .ANG..
