Oxidative conversion of cyclohexane in discharge plasma maintained with different high-voltage power sources

The influence of the pulse parameters of supply voltage in a barrier discharge reactor on the yield of incomplete oxidation of cyclohexane was studied. It was shown that the voltage pulse parameters have an insignificant effect on both the product composition of cyclohexane oxidation and on selectivity for the products cyclohexanone (40.8%), cyclohexanol (49.5%), and water (9.7%). The lowest power consumption for the conversion of cyclohexane was achieved with the use of a sine wave generator operating at a frequency of 50 Hz (3.0 kWh kg^?1) and a harmonic generator with a pulse duration of 15.3 μs and a pulse repetition frequency of 980 Hz (3.5 kWh kg^?1). The space mode of barrier discharge was realized with the use of a generator of microsecond (53 μs) alternating voltage pulses.
