摘要：

A new model for adsorption equilibria on heterogeneous surfaces is developed. First an analytical equation for single-component adsorption is derived. Then the model is extended to mixtures. The comparison with experimental data shows that single-component data can be described and extrapolated in a wide pressure and temperature range. The mixture data of a strongly real adsorpt system can be predicted with good accuracy only from single-component sorptive data and the vapor-liquid equilibrium of the considered system. A simplified model with mixture parameters gives good extrapolation to other temperatures.
