The data show a bimodal adsorption energy distribution and cannot be sufficiently modeled with a two-dimensional SAFT-VR approach. Therefore, an extension of SAFT-VR is proposed to model adsorption on heterogeneous surfaces and applied to the presented data. It can be described by the extended model with very low ARDs between 1.0% and 2.4%.||URI:||http://hdl.handle.net/11420/3909||ISSN:||0896-8446||Institute:||Thermische Verfahrenstechnik V-8||Type:||(wissenschaftlicher) Artikel|
