ABSTRACT:
A composition of matter consisting essentially of alumina and at least one compound (preferably oxide) of yttrium and/or zirconium is provided and is employed as a catalyst in the hydrotreating of a substantially liquid hydrocarbon containing feed stream (particularly a heavy oil) which also contains compounds of nickel, vanadium and sulfur. The preferred preparation of the catalyst compositions of this invention comprises at least one impregnating step using a solution containing at least one aluminum compound, which is at least partially converted to aluminum oxide in a subsequent calcining step.
