METHOD OF PREPARING DOUBLE SALT BASED CARBON DIOXIDE SORBENT AND METHOD OF ADSORBING CARBON DIOXIDE USING THE SAME PREPARED THEREBY

摘要

According to the present invention, a preparation method of an adsorbent based on double salt of alkali earth metals and alkali metals can prepare a double salt-based adsorbent which can be used as an adsorbent for carbon dioxide at high temperature and has enhanced performance of adsorbing carbon dioxide by adjusting pH using i) alkali metal carbonate or ii) alkali metal carbonate and alkali metal hydroxide salt.
