Gaseous Elemental Mercury Oxidation by Non-thermal Plasma

摘要：

The effects of the discharge tooth wheel number and the concentrations of CO2, NO and SO2 in the simulated flue gas on elemental mercury oxidation by non-thermal plasma were investigated by using a link tooth wheel-cylinder reactor energized by a negative high voltage DC power supply. The results indicated that a significant amount of elemental mercury was oxidized by non-thermal plasma. And the total mercury concentration of reactor outlet decreased as the discharge voltage increased. When the number of the discharge tooth wheel increased, more elemental mercury could be oxidized and more energy was injected into the plasma reactor. The spark voltage enhanced with the increase of CO2 concentration and the discharge voltage corresponding to the same elemental mercury oxidation rate also increased. The presence of SO2 resulted in a significant decrease of outlet total mercury concentration. NO restrained the oxidation of elemental mercury and the removal of mercury.
