CHA-type structure silicoaluminophosphate zeolite (SAPO-34) was examined as an AHP adsorbent and the influence of silicon content on its adsorption performance was evaluated. SAPO-34 with silicon content of 7.5 mol% (Functional Adsorbent Material-Zeolitc 02; FAM-ZO(2)) was selected for further testing. The water vapor adsorption isotherm of FAM-ZO2 was S-shaped and highly dependent on temperature, and a small hysteresis was observed with adsorption/desorption at 363K. No changes were observed in the properties of FAMZO(2) after 100000 cycles of water vapor adsorption-desorption, indicating that FAM-ZO(2) is Suitable durable for practical use. When the AHP was operated under conditions of T,(L)/T-M/T-H=283 K/313 K/363 K, the adsorption capacity of FAM-ZO(2) was 4.8 times and 3.8 times those of Y zeolite and silica gel.
