1. A process for making a supported hydroprocessing catalyst, comprising:
a) preparing a solution, slurry, or other mixture containing at least one Group VIB metal, at least one Group VIII metal, and an organic solvent;
b) impregnating a support with the solution, slurry, or mixture;
c) drying the impregnated support at a temperature of from 200 to 450° C. to produce a partially calcined, impregnated support having a total metals content of between about 20-60 wt %, calculated as metal oxides, and a carbon content of between about 5-20 wt % based on the weight of the partially calcined, impregnated support, the organic solvent not being present on the partially calcined, impregnated support; and
d) sulfiding the partially calcined, impregnated support that includes at least a portion of the carbon content.
