Study on Carbon Dioxide Adsorption of Carbonate Embedded on Substrates

초록

Development of effective CO2 adsorbent is getting more important to relieve the global warming problems. Various absorbents and adsorbents have been used to capture CO2. Especially, carbonate salts have been widely applied for the adsorption of CO2 due to the easy regeneration and low price. In addition, carbonate salts are safe, so they can be used even in the indoor spaces. In this study, carbonate salts were embedded on the substrate, and its CO2 adsorption performance was studied. Carbonate salts and substrate were mixed with various ratio. The effect of adsorption and desorption temperature was studied to find the optimal adsorption and desorption temperature conditions. Adsorption and desorption was cycled repeatedly to investigate the regeneration performance. The adsorbent could adsorb CO2 even after more than 20 regeneration cycles.
