specific Embodiment approach
[0088] Nitrogen gas is introduced into the inner cylinder of the low-temperature plasma reactor from the reactor inlet to remove the air in the discharge area, and the gas is drawn out from the product outlet. At the same time, the heat transfer medium is introduced into the outer cylinder from the heat transfer medium inlet, and the introduced heat transfer medium is led out from the heat transfer medium outlet. The temperature of the heat transfer medium is maintained at the temperature required by the system reaction. Then feed the raw material gas containing hydrogen sulfide into the inner cylinder of the low-temperature plasma reactor from the inlet of the reactor, and turn on the high-voltage power supply after the raw material gas flow is stable, and form a plasma discharge between the center electrode and the ground electrode by adjusting the voltage and frequency field. The hydrogen sulfide gas is ionized in the discharge area and decomposed into hydrogen and element...
