A vanadium/phosphorus mixed oxide catalyst precursor is transformed into the active catalyst for the production of maleic anhydride. The activation takes place in a fluidized bed and includes the steps of initial heating of the precursor: further heating under superatmospheric pressure: isothermal stage at superatmospheric pressure: and finally cooling the activated catalyst obtained. Catalysts activated according to this procedure show high performance in the conversion of non-aromatic hydrocarbons to maleic anhydride.
