<p>PURPOSE:To obtain a uniform titled adsorbent having improved adsorption performance and strength by kneading cement powders with a powdery absorbent agent which is wetted suitably on the surface thereof followed by pouring it into an arbitrary forming mold, drying and solidifying it. CONSTITUTION:The titled adsorbent is formed by wetting suitably the surface of the powdery absorbent such as a synthetic zeolite, an active alumina and a silica gel, etc., and adding the cement powder followed by kneading, and by pouring the obtd. powdery adsorbent into the arbitrary forming mold followed by drying to solidify. To wet suitably the powdery adsorbent, said adsorbent is dipped in water, thereby centrifuging it to suitably wet the surface of the obtd. adsorbent. The compounding ratio of the cement powder to the powdery adsorbent agent is most preferably 10-30wt% the weight dry basis of the powdery adsorbent.</p> |
