This study was designed to evaluate the effectiveness of adsorbed toluene removal using a coaxial cylindrical dielectric barrier discharge (DBD) reactor packed with a hybrid material catalyst [M/13X-gamma-Al2O3 (M: Ag, Ce, Mn, and Co)]. All experiments were conducted at atmosphere pressure and room temperature. Results showed that Ag/13X-gamma-Al2O3 (Ag/13X-Al) exhibited the highest breakthrough capacity (.14 mmol) and the highest mineralization rate (MR) for toluene decomposition (68%) at 20 kV. The kinetic model on adsorbed toluene mineralization showed a good fit with the pseudo -second -order kinetic model for all catalysts. The model determined by discharge power (P) and initial amount of adsorbed toluene (no) is expressed as: 0.0009n(0)(.2.402) . P . t = 1/n-1/n(0), where t and n denote the reaction time and the amount of adsorbed toluene, respectively. Finally, the model reliability was verified by comparing the experimental values of MR with the calculated values. (C) 2019 Institution of Chemical Engineers. Published by Elsevier B.V.
