NIOB-DOTIERTER VANADIUM/PHOSPHOR- MISCHOXIDKATALYSATOR

Disclosed is a modified vanadium/phosphorus mixed oxide catalyst for the partial oxidation of n-butane to maleic anhydride. The catalyst comprises niobium as a promoter element in an amount corresponding to an atomic ratio of vanadium to niobium in the range of 300:1 to 10:1. The catalyst exhibits i...

More Information
Summary:Disclosed is a modified vanadium/phosphorus mixed oxide catalyst for the partial oxidation of n-butane to maleic anhydride. The catalyst comprises niobium as a promoter element in an amount corresponding to an atomic ratio of vanadium to niobium in the range of 300:1 to 10:1. The catalyst exhibits improved activity, improved yield of maleic anhydride, and optimal performance from the very beginning of its catalytic lifetime.
