Gas adsorbent body, method for producing thereof, and carbon dioxide gas concentration device

Abstract

A COconcentration device has an adsorbent body formed from sheet material. Solid adsorbent particles are adhered onto at least a single surface of the sheet material and then the sheet material is wound onto itself or laminated in layers. The adsorbent body is divided into at least into a processing zone and a regeneration zone. COis adsorbed in the processing zone when the processing zone is wet with water and a COcontaining gas is passed through. The regeneration zone desorbs COwhen saturated steam is passed through. Condensation heat from the steam condensing causes COdesorption. The solid adsorbent particles may be aligned in a linear or a staggered arrangement when the solid adsorbent particles are adhered to the sheet material to follow a gas flow and form gas introduction paths between adjacent layers of the sheet material.
