<p><P>PROBLEM TO BE SOLVED: To provide an adsorbent which has large effective capacity for adsorbing water and excellent durability and is used for a heat pump, a desiccant air conditioner, a humidity-controllable wall material and a humidity-controllable sheet. <P>SOLUTION: The adsorbent comprises zeolite containing at least Al and P as elements constituting a skeleton thereof, wherein the zeolite has pores of 2.0-3.0 angstroms diameter and a three-dimensional structure consisting of an oxygen-containing six-member ring and, particularly, the zeolite has an SOD structure or an AST structure. Acicular or columnar zeolite produced by subjecting zeolite having an ERI structure to phase transition is preferably used as the adsorbent. The adsorbent is used excellently for the heat pump, particularly, for the desiccant air conditioner, the humidity-controllable wall material and the humidity-controllable sheet. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
