In order to investigate the feasibility of sequential removal NO and SO2 using non-thermal plasma and adsorbent simultaneously, the
removal of NO and SO2 from dry gas stream (NO/SO2/N2/O2) with very little O2 using non-thermal plasma was investigated using a
coaxial dielectric barrier discharge. Comparative experiments were carried out in the dry gas stream with and without Ar respectively
at O2 concentration of 0.1%. The results showed that NO could be removed remarkably and it would be enhanced in the presence of
Ar in the dry gas stream. It seems that SO2 could not be removed unless there is Ar in the dry gas stream. The mechanism of removal
of NO and SO2 in the dry gas stream was discussed.
