Since CaObased sorbents derived from naturally occurring precursors such as limestone do not reach full CaO conversion within reasonable timescales and experience rapid deactivation with increasing cycle numbers, intensive efforts are undertaken to design more effective sorbent materials. An ideal CaObased CO 2 sorbent displays a rapid

#0183;#32;Calcium looping cycle is considered as one of the most promising post combustion CO 2 capture technologies that can curb CO 2 emissions from power plants fired with fossil fuel. However the presence of SO 2 and steam in the flue gas leads to the sulfation of CaObased sorbents, and thus reduces the sorbents capacity for CO 2 capture. In this study, the effect of sorbent sulfation during
