Abstract 

Cu-SAPO-34 is a promising NOx selective catalytic reduction (SCR) catalyst. Its support, the SAPO-34 zeolite, has great effect on the catalytic performance of De-NOx. In this work, the SAPO-34 zeolites with the SiO2/Al2O3 ratio of 0.4, 0.6 and 0.8 were synthesized by a hydrothermal process. X-ray diffraction (XRD) and scanning electron microscopy (SEM) results show that the crystallinity of the SAPO-34 zeolites was improved with the increasing of the SiO2/Al2O3 ratio; and NH3 temperature-programmed desorption (NH3-TPD) results indicate that the number of the acid sites is largest when the SiO2/Al2O3 ratio is 0.8. As a result, the Cu-SAPO-34 catalyst synthesized with the SiO2/Al2O3 ratio of 0.8 presented the highest C3H6 selective catalytic reduction (C3H6-SCR) performance.
