%X The fractal characteristics of calcium based sorbents reflect the physical information and chemical performance pore structure.Based on the theory of fractal and non\|linear diffusion in pores,the fractal characteristics of pores in CaO,SO\-2 diffusion and concentration distribution in fractal pores are discussed.The influences of SO\-2 concentration distribution on the pore\|plugging and formation of inaccessible pore are analyzed with experimental results.Under the certain condition of desulfation,the fractal characteristics of sorbents determine SO\-2 concentration distribution in CaO.With the increase of SO\-2 concentration gradation in CaO,the amount of inaccessible pore volume produced in the sulfation reaction increases,and the pore utility of CaO decreases.
