The influence of reaction conditions on SO/sub 2/ oxidation in a discharge plasma reactor
In this work, we report several approaches for the removal of SO/sub 2/ using nonthermal pulsed discharge plasma processing under absence of NH/sub 3/. The gas-phase reaction was found to be less attractive due to its high energy cost. The increase in temperature decreased the SO/sub 2/ removal rate, resulting in high energy cost. In case of the wet type plasma reactor, the discharge plasma greatly enhances the liquid phase oxidation of SO/sub 3//sup 2-/ to SO/sub 4//sup 2-/. The presence of TiO/sub 2/ catalyst increased the gas phase oxidation and the liquid phase oxidation as well.
