HEAT MASS-TRANSFER DURING HYDROGEN SORPTION FROM GAS-MIXTURE BY HYDRIDE-FORMING SORBENTS

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