摘要:
Adsorption properties (enthalpy of adsorption, free energy of adsorption as well as the dispersive and specific components of free energy of adsorption) of several hydrocarbons on zeolites 13X and 5A have been evaluated by inverse gas chromatography (IGC). A parallelism between the effects of the molecular diameter on the enthalpy of immersion and the parameter of specific interaction was found for series of hydrocarbon with the same number of carbon atoms. For polar compounds, dipolar moment presents a key role on the relationship between calorimetric and chromatographic data. (C) 2005 Elsevier B.V. All rights reserved.
