Description
Summary:Removal of NO sub(x) by microwave reactor with ammonium bicarbonate and Ga-A zeolite at low temperature was analyzed. It was observed that the microwave reactor filled with NH sub(4)HCO sub(3) and Ga-A zeolite couple reduced NO sub(x) to nitrogen with best purifying efficiency of 95.45% and the best denitrification amount of 89.28 mg h super(-1). The optimal microwave power and residence time (RT) on denitrification was 259-280 W and 0.259 s respectively. Microwave denitrification effect of the experiment using ammonium bicarbonate and Ga-A zeolite was much higher than that using ammonium bicarbonate or Ga-A zeolite only. The mechanism for microwave-induced NO sub(x) reduction could be explained as the microwave-induced catalytic reaction between NO sub(x) and ammonium bicarbonate with Ga-A zeolites being the catalysts and microwave adsorbent.
