CaO sorbent dissolved in chloride molten salts was investigated to identify its CO₂ capture property. Various molten salt systems with different melting points (CaCl₂ , LiCl, LiCl-CaCl₂ , and LiCl-KCl) were used to control the operation temperature from 450 to 850ºC in order to determine the effect of the operation temperature on the chemical reaction between CaO and CO₂ . The CaO sorbent showed the best performance at 550ºC in the LiCl-CaCl₂ molten salt (conversion ratio of 85.25%). This temperature is lower than typical operation temperature of the solid-state CaO sorbent (~700ºC).
