ABSTRACT:
Catalyst compositions are disclosed containing potassium pyrosulfate, cesium pyrosulfate, supported on an inorganic oxide. The catalysts will selectively oxidize naphthalene and/or o-xylene to phthalic anhydride in a fluidized- or fixed-bed reactor system. Sulfur-containing gaseous promoter may be fed with the aromatic hydrocarbon to enhance selectivity.
