Abstract
A catalyst characterized by its ability to hydrotreat a charge hydrocarbon feed containing components boiling above 1000° F., and sediment-formers, sulfur, metals, asphaltenes, carbon residue, and nitrogen is prepared by mulling a porous alumina support with a salt of a Group VIII metal oxide and with a salt of a Group VI-B metal oxide in the presence of an acid to provide a mixture, by extruding the mixture to form an extrudate, by drying the extrudate and by subjecting the dried extrudate to hydrothermal calcination to provide the catalyst.
