CO2 Chemisorption on Li5AlO4: Effects of Sodium and Potassium Carbonate Addition

  • M. Teresa Flores-Martínez (a1) and Heriberto Pfeiffer (a1)

Abstract

In this work, Na- and K-doped β-Li5AlO4 samples were synthesized, characterized and analyzed thermogravimetrically (dynamically and isothermally), under different CO2 conditions. Additionally, chemisorption/desorption cycles were performed for the best chemical compositions and thermal conditions determined. While the CO2 chemisorption of the Na- and K-doped β-Li5AlO4 samples was improved at high temperatures (450 -700 °C), the opposite effect was observed at lower temperatures as well as in the presence of water vapor.
