| 摘 要： | A combined plasma photolysis(CPP) reactor that utilized the dielectric barrier discharge(DBD) plasma together with DBD-driven KrI excimer ultraviolet emission was applied to the decomposition of H 2 S gas.The effects of applied voltage,input current,gas flow velocity,original concentration as well as the ratio of Kr/I 2 mixture on H 2 S removal efficiency were investigated.Gas streams containing H 2 S were separately treated with single DBD and CPP reactor under the same conditions.In comparison to DBD,CPP could greatly enhance the H 2 S removal efficiency at the same applied voltage,inlet gas concentration and gas flow velocity.In addition,the reaction mechanism was also discussed in this paper.
