The Competitive Reaction in the Degradation Process of Gaseous Halons by Cold Plasma Method
|
Abstract:
In order to provide theoretical basis for applications of plasma method in degradation of pollutants,the degradation mechanism of halons(CF2ClBr,CF3Br)with cold plasma technology was studied.In oxygen free systems,the amounts of some products change dramatically with the discharge time.When enough oxygen is present,the dominant product is CF2O.Based on the studies about the reaction mechanism,the conclusion can be made that some competitive reactions take place in plasma degradation process of oxygen free halons and the participation of oxygen makes the reactions more orderly and oriented.
