【Abstract】 SO 2 is removed from the simulated gas streams using strong ionization discharge. By this method, a mass of molecules such as O 2, N 2 and H 2O are ionized into active particles such as OH etc, then the molecules of SO 2 are directly oxidized into H 2SO 4 at high temperature and without absorbent. Some factors affecting the SO 2 removal efficiency are studied in this experiment. When the residence time of gas streams flowing the reactor is 0.74 second, the contents of water and oxygen in the gas streams are 2.8% and 20.8% respectively, the experimental results show that the SO 2 removal efficiency can attain to 100%.更多还原
