Abstract
A process for effecting the desulfurization of asphaltene-containing black oil. The process utilizes a catalyst which comprises a composite of an alumina carrier material combined with one or more sulfided metallic components from Group VI-B and Group VIII wherein the catalyst particle density is within the range of from about 1.05 to about 1.24 grams per cubic centimeter. The use of the indicated catalyst particle density imparts additional desulfurization activity to the catalyst.
