The effect of varying the duration of the butane/air pretreatment on the morphology and reactivity of (VO)2P2O7 catalysts

Three vanadium pyrophosphate catalysts have been prepared by calcining vanadium hydrogen phosphate hemihydrate (VOHPO4·0.5H2O), prepared in an organic medium, for different lengths of time (40, 100 and 132h) in a n-butane (0.75%)/air mixture at 673K. The catalysts were designated VPO40, VPO100 and V...
