Non-Linear Description for the Calcined Product of Ca-Based Absorbent

Abstract:

This paper was based on pore volume distribution function which can be measured by experimental apparatus, proposed two methods of establishing microstructure distribution model for the calcined product of Ca-based absorbent, got the distribution models of pore volume, specific surface and pore length for the absorbent, and carried out comparison studies for the pore size distribution characteristics which was got both by model simulation and experiment, then compared the two models to observe the applicability of them. The result has showed that these two models both can describe the pore size and its distribution of Ca-based absorbent completely, the equivalent aperture of the logarithmic model was as same as definition, it was more appropriate when the pore radius is relatively small, and when the pore radius was relatively large, exponential model was better.
