摘要：

In this paper we present a theoretical and experimental analysis of multicomponent adsorption dynamics of hydrocarbons onto activated carbon. The mathematical model allows for the dual mode of diffusion into the particle, with surface diffusion being driven by a chemical potential rather than the usual concentration gradient. The multicomponent adsorption equilibrium is calculated using the ideal adsorption solution theory (IAST), with the single-component isotherm being described by either the Langmuir or the Toth equation. The effect of the isotherm equation on the prediction of the multicomponent sorption dynamics is investigated in this paper.
