Hydrotreating catalysts comprise a hydrogenating component and a support comprising at least one porous refractory inorganic oxide, said catalyst having BET surface area of 150 to about 190 m2/g, bulk density of at least about 0.2 g/cc, total pore volume of at least about 0.9 cc/g with mercury penetration pore volume of at least about 0.1 cc/g in macropores with radii of 600 to 25,000 Å, such surface area, pore size distribution and total pore volume being effective to give an average pore diameter of at leat 230 Åcalculated as 4V/A. Hydrotreating process comprises contacting a hydrocarbon feed with hydrogen in the presence of the aforesaid catalyst under hydrotreating conditions. The catalyst and process are particularly useful in hydrotreating feeds comprising high metals or high metals and sulfur content materials.
