ABSTRACT:
Sulfur and metal contaminants, such as nickel, vanadium and iron, are removed from hydrocarbon feedstocks, by contacting the feedstocks at an elevated temperature and pressure in the presence of hydrogen and a catalyst comprising a hydrogenation component and a support material comprised of phosphorus oxide and alumina. The hydrogenation component includes a Group VIB and/or Group VIII metal of the Periodic Table, particularly molybdenum or tungsten and cobalt or nickel. The presence of phosphorus oxide in the catalyst composition has been found to impart increased catalytic activity for demetallization of metal-contaminated hydrocarbon feedstocks such as heavy petroleum crudes and residua.
