The existence of a skin resistance for adsorbate mass transport at the surface of a pelletized adsorbent particle or at the surface of adsorbent crystals within a particle has been proven by many macroscopic and microscopic experiments. An isothermal

Most micro–mesoporous adsorbents used in practical adsorptive fluid (gas and liquid) separation processes are energetically heterogeneous. The adsorbent heterogeneity plays a significant role in establishing the shapes of the equilibrium adsorption

The Gibbsian surface excess (GSE) can unequivocally measure the extent of adsorption of a gas on a solid adsorbent. A differential iso-excess heat of adsorption based on the GSE thermodynamic framework provides a physically and thermodynamically cons

The GSE is the only experimental variable to unambiguously quantify the extent of multicomponent fluid (gas or liquid)-solid adsorption. It can be directly used to describe all practically important thermodynamic and dynamic characteristics of an ads

It is demonstrated that various combinations of models describing the adsorbed phase volume and the actual amount adsorbed (AAA) can be used to describe the experimental Gibbsian surface excess isotherm data for adsorption of a pure gas. Thus, the re

Decentralized residential power generation employing a H2 PEM fuel cell requires that essentially COx free H2 be produced on site by catalytic steam reforming of piped natural gas and then purifying the product H2 (removal of bulk CO2 and dilute CO i

The artificiality of the actual amount adsorbed (AAA) estimated from the experimentally measured Gibbsian surface excess (GSE) of a gas is discussed. The use of AAA for calculation of isosteric heat of adsorption or mixed gas adsorption isotherms usi

The effect of adsorbent heterogeneity on the performance of an adiabatic pressure swing adsorption (PSA) process for separation of bulk C2H4 from an inert gas (helium) using the BPL carbon as the adsorbent was numerically estimated employing a detail

A practical perspective of the complex and extensive subject of adsorbate mass transfer into porous adsorbents, which is important for design of adsorptive processes for separation of fluid (gas or liquid) mixtures, is given. The state of the art for

An alternative to the conventional ‘pore filling model’ for describing Gibbsian surface excess (GSE) isotherm from a liquid mixture on a porous adsorbent is proposed where the adsorbed phase volume is treated as a variable. The new model is teste
