Abstract
A dry material is synthesized by alkali metal (Li, Na and K) promoted calcium aluminate carbonates to obtain a COsorbent used at a temperature higher than 600 Celsius degrees (° C.). The key composition of the sorbents is 52˜69% of CaO, which is beneficial to capture COat 400˜800° C. A breakthrough result is achieved by using this sintering-resistant sorbent, which includes the features of 50% initial carbonation capacity and 20 folds COcapturing performance maintained after 40˜60 hours. Besides, alkali bearing material provides good velocity in COcapturing/releasing cycles; for example, by using Li and K series sorbents, 40 hours is required for 40 cycles only.
