The thermal desorption kinetic mechanism from internal micro-pores of coal is theoretically investigated by Monte Carlo simulations. It is supposed that the molecules are absorbed in the pores and can jump between adjacent ones. The desorption rates of the statistical ensemble average are calculated. The competing effect of the temperature and the adsorptive energy is analyzed. The desorption probabilities indicated that the choice of desorption energy is clear at low temperature, however, there is not clearly different between high temperature.
