Catalytic nonthermal plasma reactor for the abatement of low concentrations of benzene
Karuppiah, J.; Reddy, E. Linga; Reddy, P. Manoj Kumar; Ramaraju, B. & Subrahmanyam, Ch.
Abstract
Oxidative decomposition of dilute benzene in
air was carried out in a dielectric barrier discharge reactor
with inner metal fiber electrode that was later modified
with transition metal oxides. Typical results indicated the
best performance of the designed reactor for the removal of
dilute benzene, where conventional techniques may not be
efficient. The introduction of transition metal oxides in the
discharge zone increased the conversion of benzene and
shifted the product distribution to total oxidation. The
performance of the reactor was further improved on
humidification of air stream. The better performance of
MnOx/SMF over CoOx and SMF may be due to in situ
decomposition of ozone that may lead to the formation of
strong oxidant atomic oxygen, whereas the best performance
with TiO2/MnOx/SMF may be assigned due to the
synergy between ozone decomposition on MnOx surface
and photocatalytic action on TiO2.
