NOx removal from flue gas using direct current (DC) narrow pulsed discharge-induced non-thermal plasma (NTP) was experimentally investigated. Factors such as additives, NOx initial concentrations, residence time, reaction temperatures inside the NTP reactor, and so on were investigated to evaluate their effects on NOx removal efficiencies. The focus was on the effects of additives containing amino groups. The results showed that H2O addition enhanced NOx removal, NH3 could further increase the NOx removal efficiencies under the same conditions without an obvious NH3 slip, and N2H4 was the most effective additive by reducing NOx to N2. X-Ray diffraction (XRD) analysis of the products collected from the NTP reactor demonstrated that NOx removal inside the NTP reactor was mainly based on NOx oxidation when ammonia or H2O was used as an additive, while NOx removal was mainly based on NOx reduction with the N2H4 additive.
