A method for improving the heat and mass transfer of adsorbent is developed in this paper. A thennal conductive polyaniline was firstly used for enhancing the thennal conductivity of adsorbent pellets. A thermally conductive composite of polyaniline and adsorbent was prepared by chemical oxidative in - situ polymerization of aniline onto the surface of adsorbent particles. A thin thermal conducting layer on the surface of adsorbent particles was grown. The experimental results indicated that the thermal conductivity of this composite could be increased by approximately 4 times that of pure adsorbent. The adsorbent bed was shaped by a pressing process. This process can reduce the thennal resistance among the adsorbent particles and the contact thermal resistance between adsorbent bed and the heat exchanger. The thermal conductivity of the bed itself from the tests can be increased by 30% when the density of the solid adsorption bed is 1.5 times of its original density. Comparing the results with different methods of mixing or coating polymer

the method of polymerization is one of the best to improve the thennal conductivity of adsorbent in heat pump system.
