An experimental liquid- and gas-phase adsorption study of C1–C4 alcohols, C4–C5 isoolefins, and the tert-alkyl ethers obtained thereof over Amberlyst™35 is presented. Liquid-phase adsorption experiments were performed in a batch adsorber and gas-phase adsorption experiments were carried out in a packed-bed adsorber in a defined temperature range. Adsorption entropy and enthalpy were determined from adsorption equilibrium constants of each tracer in both liquid and gas phase. Adsorption equilibrium constants of alcohols were found to be larger than those of isoolefins and ethers. The moment technique was used to estimate micro- and macropore effective diffusion coefficients of the involved species.
