ABSTRACT:
Highly active hydrofining catalysts are prepared by ion exchanging a silica-alumina hydrogel with an ammoniacal solution of a cobalt and/or nickel compound, and thereafter compositing the undried product with an alumina hydrogel and a molybdenum component, followed by drying and calcining. The resulting catalysts are particularly active for the denitrogenation of mineral oil feedstocks.
