Conditions
- Temperature
- 1300 °C
Procedure
Granulated alumina (8 - 16 mesh) is heated at 1300° C. for 4 hours. Ferric oxalate and vanadium pentoxide are suspended in 5 parts of water, heated to 80° C., and oxalic acid is added slowly to obtain a blue-colored vanadium oxalate solution. Sodium carbonate is added and the alumina is also placed in the solution. The mixture is dried over a water bath with agitation. While air is pumped in, it is indurated in a furnace at 400° C. for 16 hours to obtain the catalyst ready for use after cooling.
Workup
- temperatureheated to 80° C.
