Kinetic equations for thermal dissociation processes

Abstract

The kinetics of thermal dissociation was studied for polydisperse systems (naturally occurring calcite and precipitated calcium carbonate) with normal and Rosin-Rammler-Sperling distributions. Experimental rate constants at selected temperatures and activation energies were calculated. The experimental results (kinetic curves) were compared with the theoretically derived curves and the usability of the selected kinetic models for description of the kinetics in such systems was estimated.
