摘要

配制了将不同含量的多壁碳纳米管（MWCNT）加入复合吸附剂13X/MgCl2中制成的新型复合吸附剂，并对其吸附、脱附和导热性能进行了测试。实验结果表明：新型复合吸附剂在闭式200℃脱附完成后，新型复合吸附剂的吸附残余量随着MWCNT含量的升高而减小，13X的吸附残余量是MWCNT含量最高的13X/MgCl2/MWCNT（CNT-5）复合吸附剂的吸附残余量的2倍，虽然MWCNT的加入不会对13X/MgCl2复合吸附剂在室温下的吸附性能有影响，CNT-5在开式、闭式的平衡吸附量可以达到0.52 g·g-1和0.38 g·g-1，分别是13X吸附量（0.24 g·g-1）的2.2和1.6倍，但新型复合吸附剂可以脱附更多的水蒸气。新型复合吸附剂的热导率随着MWCNT含量的增大而升高，CNT-5的热导率可以达到0.265 W·m-1·K-1，是13X热导率的4.9倍。

Abstract

A series of new composite adsorbents with different MWCNT mass embedded zeolite 13X/MgCl2 composite adsorbents were prepared

and the adsorption performance、desorption performance and thermal conductivity were measured. The experimental results show: Under the condition of the closed system in the 200℃

the residual adsorption of the new composite adsorbent decreases with the increase of the MWCNT content. And the residual adsorption of 13X is 2 times of 13X/MgCl2/MWCNT(CNT-5). The addition of MWCNT does not have noticeable influence on adsorption capacity at ambient temperature. The equilibrium adsorption capacity of CNT-5 could reach 0.52 and 0.38 g·g-1 in the open and closed system

respectively. And they were 2.2 and 1.6 times of 13X which equilibrium adsorption capacity is 0.24 g·g-1.The new composite adsorbent can desorb more water vapor. The thermal conductivity of the new composite adsorbent increases with the increase of MWCNT content

the thermal conductivity of CNT-5 can reach 0.265 W·m-1·K-1

which is 4.9 times of the 13X's thermal conductivity.
