In the paper we consider the problem with moving bounds that models the kinetics of hydrogen desorption from hydrides of metals. Phase change, desorption processes on the surface, size reduction, and heat absorption on the phase bound are taken into consideration. Corresponding boundary-value problem with moving bounds is presented for the experimental method of thermal desorption spectrometry (TDS). Computational algorithm based on difference approximations is developed. The results of numerical modeling are presented.
