✦ Synopsis

The addition of water vapor has a strong positive effect on the rate of ethane oxidation at 575Β°C. This effect is attributed to the role of H20 as a third body in the decomposition of Hz02 to OH radicals. Carbon tetrafluoride likewise enhances the rate of ethane conversion, although not to the extent realized with HzO. A kinetic model, based on known elementary reactions, adequately accounts for the conversions and selectivities observed as a function of H20 pressure, temperature, contact time, and 0 2 pressure.

The kinetics of the ethane pyrolysis have been studied at temperatures from 550 to 596'C and with 0 to 620,; of added nitric oxide. The rates of production of various products were studied by gas chromatography; ethylene, hydrogen, methane, nitrogen, water, nitrous oxide and acetonitrile were found
