Adsorption equilibrium and kinetics for SO2, NO, CO2 on zeolites FAU and LTA

► Adsorption isotherms of SO2, NO, and CO2 on zeolites FAU and LTA were obtained. ► Linear driving force model was applied to predict breakthrough curve successfully. ► Controlling mechanism was micropore diffusion based on mass transfer analysis. ► A new adsorption system for co-adsorbing SO2, NO and CO2 in flue gas was constructed. ► Adsorption amount of NO was improved while CO2 was replaced in co-adsorption system.
