Abstract :
In this work, an application of non-thermal plasma to one of the sulfur hexafluoride (SF6) decomposition method is experimentally investigated. A high-voltage pulsed power with a faster rise-time is used to generate the non-thermal plasma of a simple silent-type discharge reactor. The SF6 decomposition rate obtained from the experiments is characterized as an effect of inputted electric energy on the chemical reaction, and discussed in a decomposition reaction rate. In addition, a chemical treatment for some by-products of decomposed SF6 is experimentally conducted with calcium oxide (CaO) in a high binding effect on halogen products. This paper shows the experimental results of SF6 decomposition characteristics with the inputted energy effect on the reaction rate and the effective approach for the toxic by-product treatment.
