Thermal explosion of a liquid−solid heterogeneous system in a semibatch reactor

Abstract

The results of investigation of the characteristics of thermal explosion in a semibatch reactor filled with a liquid−solid heterogeneous exothermic system are presented. Two successive macroscopic stages in this reacting system are considered. The focus was on studying the effects of the rate of supply of solid reagent and the rate of its dissolution on the critical condition of thermal explosion. It is shown that a thermal explosion can occur in both the first (during solid reagent supply into the reactor) and second macroscopic stages (after supply cessation).
