【 摘 要 】

References(19)Cited-By(63)An adsorption isotherm equation is derived from a localized monolayer model in which each molecule occupies multi-site on a homogeneous surface. The resultant expression is the same as that of Honig and Mueller (1962) for single-component adsorption derived from a fractional-sized vacancy model. An expression for multi-component adsorption is presented here. The applicability of the adsorption equation is tested for systems of hydrocarbons and carbon dioxide on activated carbon, molecular sieving carbon 5A and Molecular Sieve 5A. Parameters determined from a best fit to single-component adsorption data are consistent with the physical properties of molecular sizes and the BET surface area of adsorbent. Adsorptions of binary mixtures are predicted fairly satisfactorily by use of the parameters obtained from single-component data.
