ABSTRACT:
A novel process for the demetallization of petroleum feedstocks comprising contacting a petroleum feedstock at elevated pressures and temperatures, and preferably in the presence of hydrogen, with a catalyst comprising a manganese component composited with alumina, said catalyst having a surface area in excess of 175 m.sup.2 /gm and having at least 60% of its pore volume in pores having diameters between 50 and 200 A. Preferred catalysts comprise between about 2 and 15 weight-percent manganese. Removal of more than 25%, usually more than 50%, of the organometallic impurities can be achieved.
