Gravimetric measurement of adsorption from binary gas mixtures
A precise experimental method for studying binary vapor-liquid equilibrium is to measure total pressure (P) as a function of the mole fraction in the liquid phase (2). The mole fraction in the vapor (y) is calculated from imthermal P-x experimental data using the Gibbs-Duhem equation. A similar procedure for adsorption is to measure total mass (m) of gas adsorbed as a function of the mole fract...

The adsorption of equimolar binary mixtures of hydrogen-carbon dioxide, hydrogen-methane, and methane-carbon dioxide in porous material models is determined by grand canonical Monte Carlo simulations. The material models have an adsorbent surface similar to that of nanofibers with a herringbone structure. Our main result, which is relevant for hydrogen purification and carbon dioxide capture, i...
متن کاملSemiempirical Model for Adsorption of Binary Mixtures
As it can clearly be observed in Figure 1a and 2a in the paper, the total coverage of the biggest species (in this case k = 6) has a maximum and later decreases to a limit value. This behavior is known as adsorption preference reversal (APR) and has also been observed in theoretical calculations and Monte Carlo simulations [1, 2]. The APR phenomenon usually is attributed to presence of repulsiv...
متن کاملThermostatistical description of gas mixtures from space partitions.
The new mathematical framework based on the free energy of pure classical fluids presented by Rohrmann [Physica A 347, 221 (2005)] is extended to multicomponent systems to determine thermodynamic and structural properties of chemically complex fluids. Presently, the theory focuses on D-dimensional mixtures in the low-density limit (packing factor eta<0.01). The formalism combines the free-energ...
متن کاملTheoretical Model and Phase Behavior for Binary Surfactant Mixtures I ~
A new model for micellization beha..-ior of binary surfactant mixtures in solution is presented. A packing parameter, P* , has been introduced to describe the nonrandom mixing in mixed micelles. The significant feature of this model is that it considers asymmetric behavior ofmicellization in binary surfactant mixtures and predict5 the changes in the structures of mixed micelles with concentrati...
