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.
