摘要：

An analysis of the heat and mass transfer for the dynamics of frontal nonisothermal sorption of hydrogen from inert gas in a bed of granulated hydride-forming sorbents has been made by both experimental study and by using a one-dimensional mathematical model. It is assumed that mass transfer is limited by the diffusion of molecular hydrogen in the granule pores. Axial dispersion effects are allowed for. It is shown that a satisfactory description of the experimental results can be provided using the proposed mathematical model. Heat and mass transfer characteristics of the sorption systems are determined.
