By adding expanded graphite and foaming agent into the zeolite molecular sieve and shaping, the thermal conductivity and permeability of the adsorbent were significantly improved, and the thermal conductivity of several adsorbents was measured. The SEM observation of the foaming The changes of crystal structure and microstructure of the zeolites before and after the zeolites were analyzed. The reason why the properties of the expanded graphite is the suitable additive was analyzed. TGA test showed that the mass transfer performance of adsorbents increased
