This invention relates to a process for preparing highly active hydrotreating catalysts prepared by incorporating cobalt and an element selected from the group consisting of molybdenum, tungsten and mixtures thereof, into an alumina hydrogel support. The final calcined catalysts have surface areas greater than about 300 m2/g, flat plate crush strengths greater than about 14 lbs and more than about 80% of their pore volume in pores having diameters less than about 70 Å.
A process for hydrotreating hydrocarbon feeds by contacting said feeds at a temperature in the range of from about 300°F. to about 850°F. and a pressure in the range of from about 200 psig to about 2500 psig with a hydrotreating catalyst which has a surface area above about 300 m2/g and at least about 80% of the pore volume in pores having diameters less than about 70 Å, wherein said catalyst is prepared by a process which comprises: (a) precipitating an aqueous solution of one or more aluminum salt(s) by adjusting the pH to a range between about 5.5 and...
