The use of activated carbon for separating CO/sub 2/ from other gases such as hydrogen sulfide is a potentially promising procedure. For evaluating a process of this type, analysts determined the adsorption equilibrium constant and intraparticle diffusivities for carbon dioxide using a typical activated carbon with a broad pore-size distribution. The data consisted of response measurements to pulses of carbon dioxide introduced into an isothermal bed of carbon particles. Measurements were made in the linear range of the adsorption isotherm so that the moments of the response peaks could be used to interpret the data. A major conclusion from analysis of the data was that mass transfer in the small micropores of the carbon particles could not be explained by a pore-volume mechanism.
