A catalyst, for hydrotreating heavy feedstocks, comprised of nickel and molybdenum supported on alumina having a defined pore size distribution which has been calcined at a temperature of from 621 DEG C to 705 DEG C, and a process for hydrotreating using the catalyst. Calcining of such a catalyst at such temperatures has been found to provide for effective use thereof as a hydrotreating catalyst for higher boiling feedstocks. |
