The application of temperature swing adsorption (TSA) method for De-NOx and De-SOx from flue gas was examined. The honeycomb adsorbent used in the TSA was continuously rotated to effect reiteration of the adsorption and desorption steps. In this study, silicalite was used in the De-SOx TSA plant and Co ion-exchanged ZSM-5 was used in the De-NOx TSA plant to separate SO2 and NO from artificial flue gas. By optimization of operating conditions in the single De-SOx TSA plant, the reduction efficiency of SOx was about 93%. In the combined De-SOx TSA plant and De-NOx TSA plant, the reduction efficiencies of NOx and SOx were about 80% and 83%.
