摘要
Abstract
The sulfation of a limestone modified by additives was investigated which aimed to find the causes of its enhanced sulfation capacity. A new mechanism to explain M-CaO (calcined from modified limestone) sulfation is suggested: more lattice defects are formed in M-CaO, which reduce the resistance of ion diffusion in the CaSO4 product layer, and increase the Ca-conversion. To find the further facts to support this theory, the element distribution in reacted M-CaO and the pore structure of CaO were measured. A conclusion about how lattice defects were formed in the product layers was drawn.关键词
