Oxidation of C1-C10 hydrocarbons in stoichiometric and lean mixtures with air and oxygen under the action of nanosecond discharge

The comprehensive experimental investigation of processes of alkanes slow oxidation in mixtures with oxygen and air under nanosecond uniform discharge has been performed. We have investigated kinetics of alkanes oxidation from methane to decane in stoichiometric and some lean mixtures with oxygen and air at room temperature under the action of high-voltage nanosecond uniform discharge. The discharge was initiated with repetition rate 40 Hz by the electric negative polarity pulses with 10 kV amplitude and 25 ns duration in the discharge screened tube with 5 cm diameter and 20 cm length. Mixtures initial pressures were varied in 0.76-10.6 torr range. The discharge current, electric field and input energy have been measured with nanosecond time resolution. Time of full oxidation of alkanes was determined.
