• A lab-scale dielectric barrier discharge (DBD) reactor was fabricated, and gaseous and particulate contaminant removal tests were carried out under a range of DBD reactor operating conditions: applied voltage (5.0–8.5 kV), frequency (60–1000 Hz), upstream toluene concentration (50–200 ppm) and gas flow rate (1–5 L min −1 or 0.48–0.096 s of gas residence time). The results suggested that the toluene removal efficiency (at 1 L min −1, 100 ppm) increased (up to ∼46%) either with increasing voltage (at 1000 Hz) or frequency (at 8.5 kV). The overall particle collection efficiency (at 1 L min −1) improved (up to ∼60%) with increasing voltage (at 1000 Hz) whereas the penetration of the particles increased (up to ∼40%) with increasing frequency (at 8.5 kV). The toluene removal efficiency (at 8.5 kV, 1000 Hz, 100 ppm) decreased (down to ∼29%) with increasing gas flow rate while the particle collection efficiency decreased slightly (maintaining ∼60%) regardless of the flow rate. In addition, the toluene removal efficiency (down to ∼41%) and carbon dioxide selectivity (down to ∼43%) decreased with increasing upstream toluene concentration (at 5 kV, 1000 Hz, 1 L min −1).
