摘要
The breakthrough characteristics of Kr gas in charcoal bed were studied at the temperature of 30~‘75A°C, and theoretically analyzed taking account of the Kr, carrier gas-charcoal equilibrium, and the intraparticle diffusivity. It was found that the effects of various carrier gases on the breakthrough characteristics of Kr, and the effect of temperature on the dynamic equilibrium coefficient and the selectivity of adsorption can be explained by modifying the Langmuir‘s equation for binary gas mixtures. The intraparticle diffusivity was affected by the surface diffusion, and its temperature dependence could be explained by considering the parallel pore model for the gas phase diffusion and the equation of surface diffusivity by Sladek and Gilliland et al. © 1979, Atomic Energy Society of Japan.
