Abstract
The treatment of H2S gas by the atmospheric pressure microwave plasma jet (MPJ) technology was studied. The influences of the temperature, the microwave power, the carrier(Ar) flow and total gas flow rate on H2S decomposition were investigated. The results show that, the temperature must be controlled in a certain range in order to process hydrogen sulfide; as the microwave power and the carrier gas flow increases, the decomposition rate of H2S first increases, then decreases; with the increase of the total gas flow rate, the decomposition rate of H2S falls. The maximum decomposition rate of H2S reaches to 91.32%, when the mass ratio of H2S to Ar is 10:90, the total flow is 1000 mL/min, and the microwave power is 1000 W. The production of the treatment was characterized by Raman spectroscopy and XRD (X-ray diffraction), and the results show the solid state material is high purity sulfur.
