CCl4 decomposition by gliding arc plasma: Role of C-2 compounds on products distribution

Abstract

The goal of this work is to investigate the role of existing C-2 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 Cl-2. The conversion of CCl4 into Cl-2 and (CO+CO2) reaches similar to 50% and similar to 40%, respectively. Other chlorinated compounds were suspected to be produced, such as COCl, COCl2, and C-2 compounds. In order to prove the existence of those compounds, for example, chlorinated C-2 compounds, a kinetic simulation was performed and cross-checked with the experimental results to clarify the reactions mechanism.
