Abstract
The objective of this work was to investigate NOx removal with a hybrid system consisting of a DC corona discharge and a molecular sieve at a room temperature (22 °C). In the hybrid reactor a positive DC corona discharge was generated between a hollow needle and a flat mesh. A gas mixture of N2(80%): O2(5%):CO2(15%):NO(200 ppm), simulating a flue gas, flowed through the tube with a flow rate of 1 l/min. The obtained results showed that due to adsorption of NO2 , resulted from NO oxidation, by molecular sieve placed in the corona discharge region, NOx removal increased significantly. It was also found that the number of NO molecules oxidised into NO2 does not depend on initial NO concentration. Thus, in the presence of the molecular sieve in the discharge region, the removal of NO is not controlled by gas phase chemical kinetics but by surface processes.
