 Removal of NOx by microwave reactor with ammonium bicarbonate and Ga-A zeolites at low temperatureZ.S. Wei, Z.Y. Du, Z.H. Lin, H.M. He and R.L. Qiu Energy, 2007, vol. 32, issue 8, 1455-1459 Abstract: Microwave reactor with the mixture of ammonium bicarbonate (NH4HCO3) and Ga-A zeolites was set up to study the removal of nitrogen oxides (NOx) from waste gas with excess oxygen concentration (14–19%) at low temperature (80–120°C). The results showed that the microwave reactor filled with NH4HCO3 and Ga-A zeolites could reduce NOx to nitrogen with the best purifying efficiency of 95.45% and the best denitrification amount of 89.28mgh−1. The optimal microwave power and residence time (RT) on denitrification was 259–280W and 0.259s, respectively. Microwave denitrification effect of the experiment using ammonium bicarbonate and Ga-A zeolites was much higher than that using ammonium bicarbonate or Ga-A zeolites only. The mechanism for microwave-induced NOx reduction can be explained as the microwave-induced catalytic reaction between NOx and ammonium bicarbonate with Ga-A zeolites being the catalyst and microwave absorbent.
