Abstract: The mass produced K
2 CO3 /Al2 O3 sorbents were tested for their CO2 sorption capacity by a 2000Nm3 /h (0.5MW) CO2 capture pilot plant, which was built for unit 3 of Hadong thermal power station in 2010. After the commissioning, CO2 capture pilot plant was tested with the flue gas from the power station for 60days. To assess the effect of SOx in the flue gas of coal-fired power plant on the sorbent, the new and used K2 CO3 /Al2 O3 sorbents were analyzed by FE-SEM, IC, EPMA, XRD and XPS. The results show that SOx of 10–40ppm in flue gas was reacted with K2 CO3 , but not with any other support materials, and formed K2 SO4 . And also, it is proved that the formed K2 SO4 was quite stable in the range of 180–550°C. [Copyright &y& Elsevier]- Published
