PROCESS FOR PREPARING CARBON DIOXIDE ADSORBENT AND CARBON DIOXIDE CAPTURE MODULE CONTAINING THE ADSORBENT

摘要

The present invention relates to a manufacturing method of a carbon dioxide adsorbent and a carbon dioxide capturing module comprising an adsorbent manufactured therefrom. According to the present invention, a carbon dioxide adsorbent manufactured by the manufacturing method, as a MgO composite form comprising MgO and various metal salts, has excellent performance in adsorbing carbon dioxide and thermal stability at the middle temperature in the range of 200-450°C which is a temperature range of flue gas discharged in an industrial process. In addition, in the case of applying a carbon dioxide capturing module comprising the adsorbent, an additional process for lowering the temperature of flue gas can be excluded to reduce costs for operating a process.
