Experimental concentration profiles obtained in the separation of H/sub 2/--D/sub 2/ mixtures, by selective adsorption on charcoal in a moving-bed adsorber, were used to test the validity of semi-rigorous adsorber design equations based on considerations of gas film diffusion (utilizing the linear driving force concept), solid phase diffusion (utilizing Fick's law), and axial dispersion. The adsorption equilibrium data and solid phase diffusivities used in the design equations were also measured directly in separate experiments, whereas the gas film and axial diffusion values were evaluated from published data. In general, good agreement was obtained between the experimental and theoretically predicted concentration profiles, except at the lowest flow rates investigated. (auth)
