Publication number: 20070004591Abstract: An adsorbent comprising zeolite exhibiting a moisture adsorption of at least 28 wt. % at 25° C. under a partial pressure of water vapor of 5 Torr, and exhibiting a moisture adsorption difference of 15-25 wt. % between a moisture adsorption at 25° C. under a partial pressure of water vapor of 5 Torr and a moisture adsorption at 100° C. under a partial pressure of water vapor of 15 Torr. This adsorbent is produced by ion-exchanging an exchangeable cation in a zeolite, and then, heat-treating the cation-exchanged zeolite in an air or nitrogen stream, or with steam. The adsorbent exhibits a large moisture adsorption at ordinary temperature under a relatively low partial pressure of water vapor and a small moisture adsorption at a relatively low regeneration temperature, and thus, has an enhanced effective moisture adsorption, and is used for a zeolite-water heat pump system and an open cycle moisture adsorption-desorption system.Type: ApplicationFiled: July 29, 2004Publication date: January 4, 2007Inventors: Keiji Itabashi, Masashi Harada, Koichi Sato
