Synergistic removal of nitrogen monoxide by non-thermal plasma and catalyst simultaneously.
An experimental system of De-NO with plasma-catalyst(Cu zeolite) was established to investigate the differences between De-NO with plasma-catalyst and De-NO only with plasma, to provide the instruction for selecting appropriate catalyst and operating condition. The characteristics of De-NO with plasma and De-NO with plasma-catalyst were investigated comparatively by experiments. The experimental results show that De-NO with plasma-catalyst has high NO removal rate; Cu zeolite is an effective catalyst which can promote NO removal rate in plasma remarkably; De-NO with plasma-catalyst should be operated at low temperature and the temperature has opposite effects on the function of catalyst and plasma; water vapor and O2 can increase the NO removal rate.
