The self-reactivation phenomenon of CaO-based CO2 adsorbents produced by high-temperature thermal pretreatment improves the durability of adsorbents in calcium looping process. The selfreactivation mechanisms of limestone and Nano-CaO-based adsorbents were explained as the conversion of hard skeleton to soft skeleton and the formation of cracks between Nano-grains respectively. The summarization of the recent researches about the triggering conditions is to provide reference for grasping and utilizing the self-reactivation of adsorbents.
