Phân tử zeolit 3A

5A, 4A and 3A zeolites were successfully prepared using solid seeds at pilot scale. The adsorption properties of 5A, 4A and 3A zeolites were determined by adsorption isotherm method. The results showed that water adsorption capacity and rate of 5A and 4A zeolites were higher than those of 3A zeolite. Even at low vapor pressure of water of 4 mmHg, adsorption capacity of 5A, 4A and 3A zeolites also reached about 23%, 22% and 17%, respectively, and was much higher than that of silicagel (5%).
