ABSTRACT:
A process is provided for preparing fluid bed catalysts containing the mixed oxides of vanadium and phosphorus prepared from a mixed phosphoric acid source. A pentavalent vanadium compound is introduced into an organic liquid capable of reducing the vanadium, the vanadium is contacted with the mixed phosphoric acid source, the resulting catalyst precursor is comminuted, introduced into water to form an aqueous slurry and spray dried to form microspheroidal, fluidizable particles.
