Influence of framework silica-to-alumina ratio on the water adsorption and desorption characteristics of MHI-CaX/CaY zeolite

Iwai, Yasunori; Oka, Nobuki*; Yamanishi, Toshihiko

The influence of the framework SiO$$_{2}$$/Al$$_{2}$$O$$_{3}$$ ratio from 2.0 to 10.0 of faujasite-type CaX/CaY zeolites on the water adsorption and desorption characteristics was examined. Not only the change in electronegativity but the change in pore size distribution of the zeolite affects the water adsorption and desorption characteristics of the zeolite. We found the great differences in isotherms of water on CaY7.0 (SiO$$_{2}$$/Al$$_{2}$$O$$_{3}$$ = 7.0) and on CaY10.0. A step-wise variation was observed in the desorption isotherm of water from CaY10.0. We judged the phenomenon due to the pore distribution rich in meso-pores, since similar phenomenon is observed in the case of the argon adsorption on CaY10.0.
