复合吸附剂的吸附性能是吸附制冷循环过程中的一个重要参数,基于测试整体成型复合吸附剂吸附性能的需要,本文设计搭建了一种整体成型吸附剂性能测试装置,对复合吸附剂Mg Cl2-13X进行了吸附性能测试实验。结果表明：该实验装置中吸附床外侧底部的温度变化速率较接近吸附床内部底部吸附剂的温度变化速率,二者温度变化速率相差0.01-1.9℃/min,整个吸附和脱附过程二者温度的平均值相差约3.24%,能够满足吸附剂性能测试实验的要求。吸附剂性能测试实验及电镜下吸附剂的微观结构表明：浸泡法制备的复合吸附剂的吸附性能与Mg Cl2溶液的浓度有关,Mg Cl2能够改善13X沸石分子筛的吸附性能,本实验测得当Mg Cl2溶液的浓度为15%时所制得复合吸附剂MX3性能最优,其最大吸附量为0.32 g/g,最大吸附速率0.59 g/min,相比单一吸附剂13X沸石分子筛提高了20%。

英文摘要：

The adsorption performance of composite adsorbent is a significant parameter for adsorption refrigeration cycle. An integral ad- sorbent performance testing device is designed and built to test performance of the adsorbent in this experiment. The feasibility of the device and the performance of composite adsorbent MgCl2-13X are investigated with the testing device. The result shows that the temperature change rate of bottom outside the adsorbent bed is highly near that of the adsorbent at the bottom inside the adsorbent bed. And the deviation of the temperature change rate of the two ranges from 0.01 -1.9 ℃/min, and the deviation of average of the temperatures of the two is 3.24% during the processes of adsorption and desorption, which can meet the requirements of the experiment. The experimental results and the SEM images show that the performance of composite adsorbent prepared by immersion method relates to the concentration of MgCl2 solution. MgC12 can improve the performance of zeolite 13X. And the experimental result shows that the composite adsorbent has the best performance when the concentration of MgCl2 solution is 15%. The maximum adsorption ratio of MX3 is 0.32 g/g. The water uptake rate of MX3 is 0.59 g/min, improving 20% compared to that of pure zeolite 13X.
