The treatment of H2S gas by the atmospheric pressure microwave plasma jet(AMPJ) technology and the AMPJ system were studied. The design of this AMPJ system with special nozzle structure is presented in this paper. The microwave electric field intensity and distribution with different nozzle structures were simulated at the same time. Furthermore, the treatment of H2S gas was discussed. The results show that the new nozzle structure is more conductive to the plasma jet ignition the electric field strength at the position of tip nozzle is above 1.5106 V/m when the microwave power is 500 W, which is higher than the breakdown field strength of the working gases. The maximum conversion of H2S can be up to 91.32% when the ratio of H2S and Ar is 10∶90, and the total flow is 1000 mL/min, as well as the microwave power is 1000 W. The H2S gas can be effectively disposed with the AMPJ system.
