Abstract

Abstract: The mass produced K<subscript>2</subscript>CO<subscript>3</subscript>/Al<subscript>2</subscript>O<subscript>3</subscript> sorbents were tested for their CO<subscript>2</subscript> sorption capacity by a 2000Nm<superscript>3</superscript>/h (0.5MW) CO<subscript>2</subscript> capture pilot plant, which was built for unit 3 of Hadong thermal power station in 2010. After the commissioning, CO<subscript>2</subscript> capture pilot plant was tested with the flue gas from the power station for 60days. To assess the effect of SO<subscript> x </subscript> in the flue gas of coal-fired power plant on the sorbent, the new and used K<subscript>2</subscript>CO<subscript>3</subscript>/Al<subscript>2</subscript>O<subscript>3</subscript> sorbents were analyzed by FE-SEM, IC, EPMA, XRD and XPS. The results show that SO<subscript> x </subscript> of 10–40ppm in flue gas was reacted with K<subscript>2</subscript>CO<subscript>3</subscript>, but not with any other support materials, and formed K<subscript>2</subscript>SO<subscript>4</subscript>. And also, it is proved that the formed K<subscript>2</subscript>SO<subscript>4</subscript> was quite stable in the range of 180–550°C. [Copyright &y& Elsevier]
