ABSTRACT:
A continuous process for production of maleic anhydride is disclosed wherein maleic anhydride is produced in high yield and catalyst productivity is in the range of from about 0.12 to about 0.18 pounds of maleic anyhdride produced per pound of catalyst per hour. The catalyst comprises vanadium-phosphorus-oxygen and a modifier, preferably molybdenum. The increased catalyst productivity substantially increases production rates without necessity for extensive equipment modification.
