Abstract. The development of sorbents for flue gas desulfurization in a dry mode is essential to control emission of sulfur dioxide. Based on the novel concept of "treating waste with waste", a lowcost and highly activated calciumbased sorbent (ACS) was prepared using coal fly ash, CaO and waste gypsum as the raw materials via the onestep incipient wetness impregnation method.
