Abstract: 1397119 Making fluidizable, supported molybdenum oxide-containing catalysts STANDARD OIL CO 22 June 1972 [28 June 1971] 29325/72 Heading B1E Catalysts are made by adding incrementally a sol containing SiO 2 , Al 2 O 3 , TiO 2 and/or ZrO 2 to an aqueous suspension and/or solution of a heptamolybdate or a dimolybdate and optionally an alkali metal hydroxide or nitrate at a temperature below 150‹F, spray drying the resulting slurry at a temperature below 1000‹F, collecting the dried spherical particles and calcining them. Optionally to the slurry an acid of P, As or B may be added below (150‹F) after the sol. As a further option a nitrate, carbonate, oxalate and/or acetate of an alkali metal, Mg, Ca, Zn, Cd, a rare earth metal, Sn, Nb, Ta, Sb, Bi, Te, Mn, Fe, Co and/or Ni may be added in solution to the slurry (below 150‹F) but after the acid if that is also used. Further sol may be added with the nitrate, carbonate, oxalate and/or acetate and/ or with the acid.
