This paper presents a one-dimensional simulation of the dielectric barrier discharge (DBD) in pure methane under atmospheric pressure. By employing a fluid model integrated with a set of plasma chemistry to analyze discharge behavior, we study different plasma characteristics, including applied voltage, discharge current, electron and ion density, and diverse chemical species density. Additionally, the study investigates the influences of the variation of applied voltage and the insulation layer constant on the characteristics of the DBD reactor and methane conversion. The findings reveal that increasing the applied voltage and dielectric constant influences the discharge behavior, enhancing methane dissociation.
