Abstract
Disclosed are vanadium-antimony oxide catalysts deposited as an outer layer on certain oxide support compositions. A method of making a microspheroidal fluidizable catalyst of such description is disclosed. The catalysts are useful for the oxidative conversion of o-xylene to phthalic anhydride and have good attrition resistance, as well as good activity for such reactions.
