Mn3O4 catalysts synthesized from used alkaline battery powder on Al2O3 were used for abatement of volatile organic compounds (BTX) in a non-thermal plasma system [1, 2]. The introduction of Mn3O4/ Al2O3 catalysts improved the removal efficiency of BTX. Different percentage of active phase (Mn3O4) were synthesized on Al2O3. Among these catalysts, Mn3O4(10%)/Al2O3 showed the best result for degradation of xylene, also the removal efficiency of benzene and toluene were 99% and 98%, respectively. Tests were conducted in hybrid and non-hybrid manner in different voltages (5, 10, 15 kV). In non-hybrid tests, catalysts were placed downstream of the NTP reactor. In hybrid tests, catalysts introduced into the discharge zone of NTP. Our results showed that there is no significant difference between hybrid and non-hybrid systems and both systems had a good performance specially in higher voltages for abatement of BTX.
