実験手順

The catalyst promoted with cerium (V:Ce atomic ratio=1:0.005) prepared and calcined as stated in Example 4 was used to oxidise n-butane to maleic anhydride under "fuel lean" conditions. The crystallite size of the catalyst precursor after ball milling was about 300 A. After 183 hours time on line with a feed concentration of n-butane of 1.5 mole % in air at a reactor temperature of 420° C. at a GHSV of 3100 hr-1 the catalyst gave a 49 mole % pass yield of maleic anhydride at an n-butane conversion of 89%.
