Abstract

Abstract: In this work, the decomposition of benzene was studied with CH4 using a dielectric barrier discharge (DBD) reactor. The experimental conditions such as input power, residence time, and concentration were varied to investigate the decomposition of benzene. The decomposition of benzene increased with increasing input power and residence time. The highest decomposition of benzene at 40 W and 2.86 s was 82.9%. The major gaseous products were H2 and lower hydrocarbons (LHC) and the yield of these products also increases with input power and residence time. The percentage yield of H2 increases from 0.65 to 5.18% by increasing input power from 5 to 40 W at 2.86 s. Similarly, the yield of LHC increases from 0.78 to 8.86% for benzene under the same reaction conditions. Hence, input power promoted the decomposition of tar compounds and enhanced the yield of gaseous products. However, at higher concentrations of the tar compound, decomposition efficiency and product yield decreased. The modified first-order kinetic model was used for the decomposition of tar model compound and methane carrier gas. Highlights: DBD reactor was used to decompose tar model compound (Benzene) in CH4 carrier gas. The decomposition of benzene and methane was 82.9% and 12.5% respectively. H2 and Lower hydrocarbons were the major gaseous products. The first-order kinetic model was validated for the decomposition of tar and CH4.
