Abstract
The objective of this work was to investigate NOx removal with a hybrid system consisting of a DC corona discharge and a NH3-saturated 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 1/min. The obtained results showed that the presence of NH3 as adsorbed on the molecular sieve increased NOx removal from 60 % to 75 %. Due to NH4+ ions formed on the molecular sieve surface NOx are converted into N2 and H2O, i.e. the same harmless products as in the classical Selective Catalytic Reduction method which requires high temperature.
