Kinetic equations for thermal dissociation processes

Relationships between average degree of transformation and time of dissociation were derived for polydisperse granular materials with account to the type of grain size distribution. It has been checked, under what conditions the kinetic curves obtained by numeric solution of those relationships may be described in terms of equations D1 α²=kt , F2 [1/(1 - α) - 1 =kt] and F3 [1/(1 - α)² - 1=kt].
