The present invention relates to an adsorbent having an excellent adsorptivity and a high heat conductivity, and more particularly to an adsorbent comprising a sheet containing adsorbing agent and a heat conductive sheet.
Adsorbents composed of adsorbing sheets utilizing adsorbing agents are known. Conventional adsorbents cannot efficiently perform a heat removal in adsorption operation and a heat supply in desorption operation. Therefore, difficulties are encountered in conducting an adsorption treatment, particularly when substances to be adsorbed are present in high concentrations, or in conducting a desorption operation for desorbing the adsorbed substances from the adsorbents, particularly when a desorbing gas is supplied at a low linear velocity. That is to say, break through is easy to occur in adsorption treatment, because the temperature of an adsorbing agent included in the adsorbent rises due to the heat of adsorption, so the adsorptivity is lowered. On the other hand, in case of desorption operation, the temperature of the adsorbing agent remarkably drops due to heat removal by desorption, so the desorption characteristics are lowered.
It is an object of the present invention to provide an adsorbent having a high adsorptivity and a high heat conductivity.
A further object of the present invention is to provide a sheet-like adsorbent having a high adsorptivity and a high heat conductivity.
Another object of the present invention is to provide an adsorbent assembly comprising a plurality of sheet-like adsorbents, from which the heat of adsorption can be efficiently removed and to which a heat can be efficiently supplied so as to be able to efficiently conduct a desorption operation.
These and other objects of the present invention will become apparent from the description hereinafter.
