Reaction Steps

To 30 ml of water is added 0.45 gram of vanadium pentoxide, 0.99 grams of oxalic acid and 2.26 grams of formamide at room temperature with stirring to form vanadium oxalate, and this solution was then mixed with 6.0 grams of titanium dioxide rutile powder (which were first dispersed in 10 ml of water). The resulting mixture was heated with stirring at 65° C. to evaporate the majority of the water, followed by drying in an oven (101 kPa) at 110° C. for 16 hours. The resulting solid was then calcined in a flowing oxygen gas stream at 450° C. for 2 hours, followed by crushing and screening to form -20+40 mesh particle size. The catalyst formed by the above impregnation procedure was determined by calculation (based on the vanadium salt and the weight of the titanium dioxide particles) to contain 7 wt.% V2O5 on the TiO2.
