ABSTRACT:
Carbonates and/or hydroxides of one or more of the Group VIII metals, cobalt and nickel, are reacted with molybdic acid in aqueous suspension to form a slurry of crystalline cobalt and/or nickel molybdate, which slurry is then reacted with gelatinous boehmite alumina, then extruded, dried and calcined. The method eliminates the use of ammoniacal solutions, washing and/or heating steps to remove undesired anions or cations, and requires but a single drying and calcination. The resulting catalysts are found to be very active for the desulfurization and denitrogenation of mineral oils.
