Studying and finding techniques to treat CS compounds is an extremely urgent task. This article presents the results of research on the treatment process of CS and hydrolysis products of CS by incineration technology combined with oxidation catalysts. The CS and hydrolysis products of CS are removed from the chlorine atom by KOH/PEG solution to prevent dioxin formation before burning. The results showed that the effectiveness of the removal of chlorine for CS and hydrolysis product of CS depends on temperature, time, PEG grade and KOH/PEG mass proportion. The survey at a temperature of 70oC, after 3 hours, the mass proportion of KOH/PEG400 (30%, 50%) and the removal efficiency of chlorine for CS and hydrolysis product of CS were 94.8% and 95,4%, respectively. The hydrolysis product without removing chlorine and after removing chlorine was burned on a furnace system in the presence of Fe3O4 catalyst proportion was 0.5% and at a temperature was 600 oC, the conversion efficiency into CO2 achieving 92.5% and 97.1%, respectively.
