At the beginning, the non-treated limestone and oxalic acid-treated limestone have higher CO 2 uptake than oxalic acid-treated limestone with Al 2 O 3 and later decays over the 20 carbonation-calcination cycles. The oxalic acid-treated limestone with Al 2 O 3 has low surface area which can lead to low CO 2 adsorption capacity (Younas et al., 2016).
