Static Adsorption, by Activated Carbons, of Vapour Mixtures Corresponding to Immiscible Liquids

Static Adsorption, by Activated Carbons, of Vapour Mixtures Corresponding to Immiscible Liquids

It is shown that the static adsorption of benzene and water vapours by a typical industrial active carbon can be described by the model of independent co-adsorption proposed for compounds which are not miscible in the liquid state. The model assumes that the vapours are adsorbed according to their r...
