CCL₄ DECOMPOSITION BY GLIDING ARC PLASMA: ROLE OF C₂ COMPOUNDS ON PRODUCTS DISTRIBUTION

Abstract

The goal of this work is to investigate the role of existing C₂ compounds in the plasma reactions of carbon tetrachloride (CCl₄) decomposition. The experiment of CCl₄ decomposition was carried out by gliding arc plasma. The decomposition products were dominated by CO, CO₂, and Cl₂. The conversion of CCl₄ into Cl₂ and (CO + CO₂) reaches ∼ 50% and ∼ 40%, respectively. Other chlorinated compounds were suspected to be produced, such as COCl, COCl₂, and C₂ compounds. In order to prove the existence of those compounds, for example, chlorinated C₂ compounds, a kinetic simulation was performed and cross-checked with the experimental results to clarify the reactions mechanism.
