Modification of Kinetic models for the description of thermal dissociation processes in polydisperse system.

Abstract:- Relationships have been established between the average transformation degree and the dissociation time for polydisperse granular material, taking into account its grain size distribution. It has been checked in which cases the kinetic curves, obtained by a numerical solution, can be described in terms of the chosen F1, F0,D1 equations (models). Key-Words:- kinetics, kinetic models, thermal dissociation of solids, polydisperse system.
