| Abstract |
This paper proposes an effective decomposition method of trichloroethylene using pellet packed-bed non-thermal plasma reactor and catalyst. For that, two types of reactors filled with manganese dioxide and alumina pellets are designed. When MnO₂ packed reactor is used, TCE decomposition rate is high due to the generation of oxygen atom radicals at the swiace of catalyst during ozone decomposition. In addition, When Al₂O₃ packed reactor is used, TCE is oxidized into DCAC and it did not decomposed into small molecules such as COx and Cl₂. However, the plasma processed gas using Al₂O₃ packed reactor is passed through the MnO₂ catalyst reactor, which is placed at the downstream of plasma reactor, the decomposition rate increased as well due to oxygen atom radicals through ozone decomposition. Therefore, the adequate use of MnO₂ catalyst in the plasma process is very promising way to increase the decomposition efficiency. |
