摘要

硅铝沸石分子筛在吸附领域应用广泛，其亲、疏水性能对吸附性能影响较

大，但硅铝沸石分子筛在不同条件下的水蒸气动态吸附性能尚不明确。采用不同硅铝比（

(SiO

(Al

) = 30、135或679）的Beta分子筛（Beta-30、Beta-135 和Beta-679）作为研究对象，先采用XRD、FT-IR和TG等对其进行了表征，然后在不同温度和相对湿度（

）下分别进行了Beta-30、Beta-135和Beta-679的水蒸气吸附容量和相应动力学分析。结果表明，当温度为25 ℃或35 ℃、

小于80%时，Beta-679的吸附容量最低。当温度为15 ℃、

为5%~10%时，Beta-679的平衡速率最快。当温度为15 ℃、

为50%~70%时，Beta-30、Beta-135和Beta-679的平衡速率表现出较大区别（Beta-135的平衡速率远小于Beta-30和Beta-679的平衡速率）。

Abstract

Silica-aluminum zeolite molecular sieve is widely used in adsorption field

and its hydrophilic and hydrophobic properties have great influence on adsorption properties. Howerer

the dynamic adsorption properties of water vapor in silica-aluminum zeolite molecular sieve under different conditions are still unclear. Beta molecular sieves (Beta-30

Beta-135 and Beta-679) with different silicon to aluminum ratios (

(SiO

(Al

) = 30

135 or 679) were used as research objects

and were characterized by XRD

FT-IR and TG

etc. Then the water vapor adsorption capacities and corresponding kinetics of Beta-30

Beta-135 and Beta-679 were analyzed under different temperatures and relative humidities (

)

respectively. The results show that Beta-679 has the lowest adsorption capacity when temperature is 25 ℃ or 35 ℃ and

is less than 80%. The equilibrium rate of Beta-679 is the fastest when temperature is 15 ℃ and

is 5% to 10%. When temperature is 15 ℃ and

is 50% to 70%

the equilibrium rates of Beta-30

Beta-135 and Beta-679 show great difference (the equilibrium rate of Beta-135 is much smaller than that of Beta-30 and Beta-679).
