Abstract

NaA, NaY and NaZSM-5 zeolites were characterized by CO₂ adsorption at 273K. The results showed that the microporous volumes basing on D-A model were in agreement with the data form literature. The Horvath-Kawazoe (HK) models (HK_sphere, HK_cylinder and HK_slit) were used to analyze pore size distributions (PSDs). It was shown that the HK_sphere model correctly described the pore structure of NaA, NaY and NaA+NaY mixture, while HK_cylinder model could well characterize the pore structure of NaZSM-5. In the case of NaA+NaZSM-5 mixture, including the spherical and cylindrical pores, both HK_sphere and HK_cylinder model were needed to get PSDs.
