Abstract: A process for activating fluid bed catalysts useful for producing maleic anhydride from 4-carbon atom hydrocarbons consists in contacting the fluidized catalyst containing the mixed oxides of vanadium and phosphorus with oxygen and a reducing gas at least partially combustible with oxygen at elevated temperatures sufficient to cause such combustion, the molar ratio of reducing gas to oxygen being below the stiochiometric ratio required for complete combustion of the reducing gas. The activated catalysts are used to producing maleic anhydride from 4-carbon atom hydrocarbons.
