Abstract:
The microstructure and the pore size distribution of 3 kinds of shell and 1 kind of limestone were measured with electronic scanning microscope and pore master mercury porosimeter, and the desulphurization characteristics of above absorbents were studied with thermal-gravimetric analyzer. As a result, the grains of calcium from shell like tortuous flakes, with pore diameter above 0.2 micron and higher pore volume, while the grains from limestone like particles, with pore diameter between 0.01 to 0.16 micron and lower pore volume, but the surface area were very high. The bigger pore which was above 0.2 micron in shell had many advantages, such as fewer air-blocked pores, lower gas diffusing resistance, almost simultaneous and completed reaction. So, finally the calcium conversation ratio of the shell was greater than that of the limestone. On the other hand, while the gas diffusion was meted, it was effective for desulphurization to reduce the pore size and to increase the surface area.
