| Abstract: | In this paper, a fluidized bed and TGA were employed to perform the flue gas desulfurization; the dynamic characteristics of pores or pore structure were analyzed with the help of mercury porosimeter for different reactant solid samples having porous property under variant conditions. The experimental measurements indicated that the pore structure and its distribution greatly affected or even dominated the dynamic process. The distributed pore model was developed to describe the dynamic characteristic of flue gas desulfurization. The model indicated that the pore structure, especially pore distribution, most\|favored radius, governed the desulfurization process, and the final conversation rate was completely dependent upon the initial porosity of solid desulfurizer. The experiment data were agreed well with the model prediction. |
