Abstract: | The kinetics of convective drying (regeneration) of different types of adsorbents-dessicants with different geometric parameters
has been studied. It is shown that adsorbents of a “channel” (cellular) type have a long constant-rate stage of drying, whereas
a granulated polydisperse adsorbent is mainly dried at a variable rate. Adsorbents having a maximum water yielding capacity
have been revealed. It has been established that the velocity of a drying gas flow substantially influences the process of
moisture extraction from all types of adsorbents. In order to describe the kinetic curves of the given phenomenon, a model
of a relaxation kinetic equation that quite satisfactorily describes the kinetics of drying of the adsorbents studied was
used.
