Abstract
A micro-grained limestone was used to study the effects of such variables as temperature and time of exposure to the gas on surface area, pore size distribution and porosity of calcined particles under the conditions applicable to a practical unit for fluidized-bed combustion and desulphurization. The mean pore size was correlated as a function of the temperature of calcination. An optimum temperature was found for the sulphation reaction of the carbonate.
