Abstract

A catalyst for hydrofining fraction oils, comprises an alumina carrier and at least one metal and/or thereof oxide of Group VIB and at least one metal and/or thereof oxide of Group VIII supported on said alumina carrier. The pore volume of said alumina carrier is not less than 0.35 ml/g, in which the pore volume of the pores having a diameter of 40-100 angstrom accounts for more than 80% of the total pore volume, the alumina carrier is prepared by a special process. The catalyst possesses relatively high hydrogenation activity.
