Beschreibung
Zusammenfassung:	A Vanadium/Phosphorous 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 a) initial heating of the precursor b) further heating under superatmospheric pressure c) isothermal stage at superatmospheric pressure and finally d) cooling the activated catalyst obtained. Catalysts activated according this procedure show high performance in the conversion of non aromatic hydrocarbons to maleic anhydride.
