[0088] Nitrogen gas was introduced into the inner barrel of the low temperature plasma reactor from the reactor inlet to purge air in the discharge area, and the gas was drawn out from the product outlet. At the same time, the heat-conducting medium is introduced into the outer cylinder from the heat-conducting medium inlet, and the introduced heat-conducting medium is led out from the heat-conducting medium outlet. The temperature of the heat transfer medium is maintained at the temperature required for 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. After the gas flow of the raw material is stable, turn on the high-voltage power supply, and adjust the voltage and frequency to form a plasma discharge between the center electrode and the ground electrode. field. The hydrogen sulfide gas is ionized in the discharge area and decomposed into hydrogen and ...
