| Abstract: | In order to find out the mechanism of desulphuization and mass transfer process,the microstructure of sorbents in bed,the distribution of Calcium and Magnesium and the line-area distribution of sulphur element for a tiny zone in reaction product layer are investigated by the use of the scanning electronic microscope and the wave-energy spcctrum analysis.The reaction thickness and its variation with SO_2 concentration obtained is compared with that measured by thermogravimetric analysis.The relatively audio-visual scientific basis for better understanding the desulphurization mechanism,mass transfer process and their variation regularities are provided. |
