Abstract
The adsorption characteristics of a packed bed of carbon granules were determined under dynamic flow conditions for individual vapors and binary vapor mixtures of various compositions and concentrations. Carbon tetrachloride, chloroform, and benzene and binary mixtures of these vapors, with wide variations in the mole fraction of each vapor, were used. We found that the adsorption space occupied by each vapor was proportional to its mole fraction in the mixture; that is, the vapor's adsorption space was reduced from the adsorption space it would have occupied at the same relative pressure if the carbon bed had been exposed to each vapor separately. The diminished effectiveness of the carbon for one vapor due to the presence of another was quantitatively predicted for binary mixtures by applying this finding to previously established adsorption relationships.
