Abstract:
A carbon dioxide adsorbent may include a double salt having a first metal salt and a second metal salt. The first metal salt may include a first metal selected from Ca, Sr, and Ba. The second metal salt may include a second metal selected from Li, Na, K, Rb, and Cs. The present disclosure also discloses a process for preparing the carbon dioxide adsorbent and a method of separating carbon dioxide using the same.
Abstract:
A carbon dioxide adsorbent may include a chabazite zeolite containing an alkali metal ion or alkaline earth metal ion. The chabazite zeolite may have a Si/Al mole ratio of about 1 to about 9.9 and mesopores. The carbon dioxide adsorbent may be included in a carbon dioxide capture module. The carbon dioxide adsorbent may also be used in a method of separating carbon dioxide.
Abstract:
An adsorbent for carbon dioxide may include an inorganic oxide porous structure having a plurality of mesopores and an active compound bound to the surface of the mesopores. The active compound may be selected from an alkali metal-containing compound, an alkaline-earth metal-containing compound, and a combination thereof. Various example embodiments also relate to a method of preparing the adsorbent for carbon dioxide and a capture module for carbon dioxide including the adsorbent for carbon dioxide.
