Simplified Crossover Droplet Model for Adsorption of Critical and Supercritical Fluids in Slit Nano-Pores

S.B. Kiselev and J.F. Ely

Keywords:
adsorption, crossover theory, fluids, nanopores

Abstract:
We present a a simplified crossover droplet (SCD) model for the excess adsorption of pure fluids at a flat solid-liquid interface in the volume and slit nano pores, which reproduces scaling behavior of the excess adsorption in the critical region, and is reduced to the classical, van der Waals-type analytical model far away from the bulk critical point. In developing this model, we used the density-functional theory (DFT) approach for the order parameter profile calculations with a generalized corresponding states model for the local free-energy density [1]. The SCD model well represents the available experimental adsorption data for Kr/graphite, C2H4/graphite, C3H8/griphite, CO2/silica, and SF6/graphite systems in the volume, slit nanopores, and CO2/silica gel system as well
