Abstract: A CO2 concentration 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. CO2 is adsorbed in the processing zone when the processing zone is wet with water and a CO2 containing gas is passed through. The regeneration zone desorbs CO2 when saturated steam is passed through. Condensation heat from the steam condensing causes CO2 desorption. 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.
