为满足高效旋转式除湿技术的要求，采用水热法制备硅铝酸盐吸附剂，揭示了搅拌时间对吸附性能的影响． 通过 N₂ 吸附 － 脱附等温线和 TEM、XPS、XＲD 和 FT-IＲ 等测试对吸附剂结构与形貌进行表征，利用动态水蒸气吸附分析仪测试吸附剂对水蒸气的吸附 －脱附性能． 结果表明:随着搅拌时间的延长，吸附剂的比表面积、孔容和表面硅铝原子比逐渐增大，而平均孔径逐渐减小，水汽吸附性能有所增强，且吸附剂脱附温度仅为 360 K，在
低湿度(ＲH≤40%)下的吸附性能强于 3A 分子筛．

In order to meet the requirements of the efficient rotary desiccant technology，the aluminosilicate was
synthesized via the hydrothermal method，and the influence of the stirring time on the adsorbent properties was revealed． Then，the structure and morphology of the absorbent were characterized by using the N₂ adsorption-desorption isotherm and by means of TEM，XPS，XRD and FT-IR，and the adsorption/desorption properties of the adsorbent on water vapor were determined by using a dynamic vapor sorption system (DVS-STD)． Experimental results show that，as the stirring time increases，the specific surface area，pore volume and surface Si/Al ratio of the adsorbent gradually increase，the average pore size gradually decreases，and the absorption property of the adsorbent on water vapor is improved，and that the adsorbent has a low desorption temperature of 360 K，and the absorption property of the aluminosilicate on water vapor is better than that of zeolite 3A at a low relative humidity (RH≤40 %)．
