The addition of water vapor has a strong positive effect on the rate of ethane oxidation at 575°C. This effect is attributed to the role of H 2 O as a third body in the decomposition of H 2 O 2 to OH radicals. Carbon tetrafluoride likewise enhances the rate of ethane conversion, although not to the extent realized with H 2 O. A kinetic model, based on known elementary reactions, adequately accounts for the conversions and selectivities observed as a function of H 2 O pressure, temperature, contact time, and O 2 pressure. © 1994 John Wiley & Sons, Inc.
