In this study, we investigated the cause of the decrease in activities of SCR catalyst used for the burner reactor at a scale of using X-ray diffraction (XRD), brunauer-emmett-teller (BET), atomic emission spectroscopy inductively coupled plasma (AES ICP), temperature programmed reduction (-TPR), and temperature programmed desorption (-TPD) analysis. Since the crystallization of the and phase transition of did not occur, it was concluded that the catalyst was not deactivated by the thermal effect. In addition, from the elemental analysis showing that a large quantity of calcium was detected but not sulfur, the deactivation process of the SCR catalyst was mainly caused by Ca but not by . The calcium was also found to decrease the catalytic activity by means of reducing adsorption.
