Abstract
Heterogeneous reaction is considered to be main mechanism in desulfuri zation from the flue gas by low temperature plasmas. The radical SO3- plays a major part in oxidizing sulfite ions to sulfate ions in refere nce to Huie's proposal. Solving the kinetic equations reveals that the hydroxyl radicals absorbed in the liquid phase may contribute over 85 % of desulfurization rate, which is over ten times of that due to gas phase reactions. The predicted area factor effect is proved by the exp eriments.
