Catalytic Reduction of SO2 Using Pulse Discharge

The basic principle of a kind of new technology, the catalytic reduction of SO2 using pulse discharge, including the principle of catalytic reduction of SO2 and pulse discharge, is analyzed, and some cursory theories and chemistry equations are presented in this paper. This technology can be considered as catalytic reduction assisted with pulse discharge. It is possible to reduce catalytically SO2 at normal temperatures. The present status of the study is introduced, and two aspects about research of plasma and catalyst are discussed. One aspect is making higher performance catalysts by the plasma technology, the other aspect is how plasma can enhance the catalytic activation. Then the key technological points are put forward such as: the high voltage pulse power supply, the preparation of catalyst and the study of mechanism. This technology is feasible due to its merits. The direction of future research in catalytic reduction of SO2 using pulse discharge is also presented in detail.
