    Abstract

    The process of conversion of C2-C4 hydrocarbons was investigated, using nanosecond pulses (135 kV, 3 ns), in a plasmochemical reactor with a corona-streamer discharge. The principal products of conversion are acethylene, ethylene, and propylene. The conversion degree and the composition of the reaction products depend on the electrode gap spacing and its attendant corona-streamer-to-spark transition. The power demand for the production of alkenes is 8-10 kW·h/kg. The conversion of paraffin hydrocarbons in nonequilibrium-plasma discharges with the purpose to produce lower alkenes of the ethylene and propylene type has long attracted the attention of researchers owing to the simplicity of this process which can readily be realized in high-frequency, microwave, glow, barrier, and corona discharges. However, the need for reduced pressures for the first three types of discharge is an essential disadvantage from the technological viewpoint. Recently, extensive studies have been performed with the use of the corona-streamer discharge that allows one to produce highly nonequilibrium plasmas at atmospheric pressure and to deliver large amounts of energy to a gas. This discharge is also used to treat industrial waste gases with the purpose to burn up toxic organic impurities and remove nitrogen and sulfur oxides. It has been shown that in going from microsecond durations of the applied voltage pulse to durations of some tens of nanoseconds (with the voltage rise rate being increased from 1011 to 5·1012 V/s) the rates of plasmochemical reactions increase substantially due to the increase in electron temperature Te in the nonequilibrium gas-discharge plasma. The goal of the present study was to investigate the efficiency of the conversion of lower alkanes in the plasma of a nanosecond corona-streamer discharge.
