Abstract: The effects of leaching parameters on the composition of the adsorbent derived from steel slag is studied in this study, and the CO2 capture characteristics and cyclic stability of the derived adsorbent under the effect of the element composition are also investigated. The results show that well‐ developed pore structure of derived adsorbents are obtained compared with the raw steel slag. The calcium content in the adsorbent significantly increases after leaching, improving the CO2 capture ability of the derived adsorbents. The Fe, Si, and Al contents decrease, while the Mg and Mn contents change little after leaching, which increases the cyclic stability of the derived adsorbent compared to that of analytically pure CaO. Under the optimized working conditions, the initial CO2 capture ability of the derived adsorbent is 0.61 gCO2/g‐sorbent. The deactivation ratio of the sample after 20 cycles is 52.46%, showing good performance compared to that of analytically pure CaO. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.
