Modelling adsorption isotherms of binary mixtures of carbon dioxide, methane and nitrogen

Abstract

A molecular-based approach for modelling mixtures adsorbed onto solid surfaces using the Statistical Associating Fluid Theory for Potentials of Variable Range (SAFT-VR) for three- and two-dimensional systems is presented in this work. The theory is used to describe the adsorption of binary mixtures of carbon dioxide, methane and nitrogen onto dry activated carbon, describing the overall adsorption phase diagram reported for these systems even at high pressures.
