CARBON DIOXIDE ADSORBENT, THE MANUFACTURING METHOD THEREOF, AND THE USE METHOD THEREOF

Abstract

A method for manufacturing a carbon dioxide adsorbent is provided. The method comprises steps of providing a limestone having a first specific surface area, treating the limestone with acid solution to obtain a first substance having a second specific surface area larger than the first specific surface area, at the same time reacting the first substance with an anti-sintering agent to obtain a second substance, and calcining the second substance to obtain the carbon dioxide adsorbent containing calcium-based oxides.
