Adsorption

The density functional theory (DFT) has been applied to describe confined fluids with great success in the literature. However, the usual numerical methods to solve the Euler–Lagrange equations of the grand potential functional are inefficient …

CO ₂ in 13X beads is macropore diffusion limited as reported by several independent studies. These include frequency response systems [ 1 – 6 ]; volumetric and ZLC measurements [ 7 ]; and microcalorimetry [ 8 ]. Of particular relevance is the study …

A usual experimental procedure for evaluation of solid–liquid adsorption isotherm models consists in varying the initial concentration of adsorbate, while keeping constant the ratio between the solution volume and adsorbent mass. However, one may …

This paper analyses the growth of the adsorbed layer during the course of $$N_2$$ N 2 adsorption verified in two types of elliptical pores, oblates and prolates, by means of the Broekhoff de Boer theory. The information provided by the value of …

In this study seven adsorption azeotropes involving binary systems and zeolite-based adsorbents were systematically investigated. Pure component isotherms and mixed-gas adsorption data were taken from published literature except for the …
