Gas phase oxidation catalyst with defined vanadium oxide particle size distribution |
摘要 |
A process is described for producing a catalyst for gas-phase oxidations, in which a suspension of TiO2 and V2O5 particles is applied to a fluidized inert support, wherein at least 90% by volume of the V2O5 particles have a diameter of 20 mum or less and at least 95% by volume of the V2O5 particles have a diameter of 30 mum or less. The defined particle size distribution of the V2O5 allows a high coating efficiency.
