Application of plasma technology with different voltage in the removal of BTX using treated used battery powder as nano-catalyst

Mn3O4 catalysts synthesized from used alkaline battery powder on Al2O3 were used forabatement of volatile organic compounds (BTX) in a non-thermal plasma system [1, 2]. Theintroduction of Mn3O4/ Al2O3 catalysts improved the removal efficiency of BTX. Differentpercentage 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 efficiencyof benzene and toluene were 99% and 98%, respectively. Tests were conducted in hybrid andnon-hybrid manner in different voltages (5, 10, 15 kV). In non-hybrid tests, catalysts were placeddownstream of the NTP reactor. In hybrid tests, catalysts introduced into the discharge zone ofNTP. Our results showed that there is no significant difference between hybrid and non-hybridsystems and both systems had a good performance specially in higher voltages for abatement ofBTX.
