Abstract
The thermal explosion of a heterogeneous liquid–solid reaction system in a semibatch reactor was simulated with consideration for the temperature dependence of distribution coefficient. It was shown that this temperature dependence strongly influences the critical conditions of ignition. At weak temperature dependence of a distribution coefficient in a subcritical mode, the process was a degenerative one. Unlike a classical degenerative thermal explosion of homogeneous systems, which is determined by the small values of thermal effects and activation energies, degeneration in heterogeneous systems is determined by the laws of interphase mass transfer.
