Limestone calcination pore size distribution

Calcination of limestone has been chosen as a model reaction and pore size distributions of the limestone particles are determined at different extents of calcination at different temperatures. Although the calcination reactions have been investigated for ages there are still questions about the actual mechanism of such reactions. The literature does not involve the structural variations.

Reyes and Jensen [1987] modeled the sulfation of calcined limestone by SO2, accounting for the pore size distribution and the possibility of pore plugging by expansion of the solid volume fraction. The continuity equations were of the type (4.4-2) and (4.4-7). The evolution of the pore size distribution with time was obtained through the simultaneous solution of a population balance equation (see Froment and Bischoff [1990], Chapter 12, Example 12.7.2). The evolution of the...
