As shown below, the developed LiNaZr adsorbents showed relatively stable CO2 capture performance after 20 cycles. The two adsorbents were prepared at different calcination temperature (650 and 700 °C). In general, it is noted that LiZr based adsorbents have a much lower capacity of CO2 capture compared to CaO-based adsorbents. In addition, LiZr adsorbents require much long reaction time. For example, in this work, the adsorption time was 90 mins (at 500 °C), while the desorption time was 50 mins (at 700 °C). Therefore, LiZr based adsorbents might do not have advantages to CaO based sorbents, unless some specific circumstances are presented requiring LiZr-based materials.
