ABSTRACT:
A catalyst composition for the hydrogenation of heavy hydrocarbon oil, where the catalyst composition comprises at least one active ingredient for hydrogenation supported on a porous alumina carrier and has the following characteristics: (1) the total volume of the pores therein is from 0.4 to 1.0 ml/g; (2) the mean pore diameter of pores having a pore diameter of from 5 to 400 .ANG. is from 60 to 140 .ANG.; (3) the volume of pores having a pore size within .+-.25% of the mean pore diameter of pores having a pore diameter of from 5 to 400 .ANG. is from 60 to 98% of the volume of pores having a pore diameter of from 5 to 400 .ANG.; (4) the volume of pores having a pore diameter of from 400 to 5000 .ANG. is from 2 to 9% of the total volume of the entire pores; (5) the ratio (mm.sup.2 /mm.sup.3) of the outer surface area of a molded catalyst powder to the volume thereof is from 4 to 8; and (6) all points in the interior of the molded catalyst particle are positioned within 0.05 to 0.6 mm from the outer surface thereof. A process for producing the catalyst composition is also disclosed. Further, a process for hydrogenating heavy hydrocarbon oil, which comprises contacting the heavy hydrocarbon oil with the catalyst composition in the presence of hydrogen is disclosed.
