V/Al/O oxides have been prepared and tested as catalysts for the ammoxidation of propane into acrilonitrile at 500°C. The high efficiency of these catalysts, which were partially nitrided under catalytic reaction conditions, is confirmed. The best catalysts characterized by a V/Al ratio around 0.30, exhibited selectivity to acrilonitrile of 51% at 58% conversion. Testing at low conversion showed that...
