Abstract

The kinetics of n-butane oxidation over a vanadium phosphate catalyst with a phosphorus to vanadium rate of 1.1 were studied under different levels of water vapor in the gas phase, in order to assess the effects of water vapor on the activity and selectivity characteristics of this catalyst. The water vapor appears to accelerate the development of the solid structure, in particular the evolution of the catalyst surface area. Further, it leads to an enhancement in the selectivity towards partial oxidation and a decline in the activity towards butane oxidation, when compared to corresponding dry feed conditions.
