Abstract
Experimental measurements of the reaction of sulfur dioxide and oxygen with limestones have demonstrated substantial influence of the geologic origin of the stone, its porosity and particle size, gaseous concentration of sulfur dioxide, and temperature on the course of reaction and the conversion (that is, the degree of utilization of the limestone content of the particles as a sorbent for sulfur dioxide). A mathematical model including intraparticle transport and chemical reaction within the particles (grain theory) has been developed to simulate this sulfur dioxide sorption reaction.

The processes in a fluidized-bed combustor are analysed, and equations are written to express the absorption rate of sulphur dioxide by limestone in admixture with the fuel feed. The procedure adopted for solution of the equations is described, and some of the results predicted by the model are brie
Stone is one of the most important structural and monumental materials. The main aim of preservation of stone objects is to prevent their deterioration caused by external conditions and to increase their general resistance to changing environmental conditions. Many substances in various forms are be
