Capillary condensation and adsorption of binary mixtures.
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 کاملGas adsorption and capillary condensation in nanoporous alumina films.
Gas adsorption and capillary condensation of organic vapors are studied by optical interferometry, using anodized nanoporous alumina films with controlled geometry (cylindrical pores with diameters in the range of 10-60 nm). The optical response of the film is optimized with respect to the geometric parameters of the pores, for potential performance as a gas sensor device. The average thickness...
متن کاملDynamics and Separation-based Adsorption of Binary Mixtures of CH4, CO2 and H2S on MIL-47: GCMC and MD Studies
This study aimed to investigate the adsorption of CH4, CO2, H2S at a temperature of 298.15 K and pressurerange of 0.1 to 30 atm, and compare the results with experimental data for MIL-47 using GCMC. Themaximum CH4, CO2 and H2S adsorptions were 3.6, 10.45, and 12.57 mol.kg-1, respectively. In addition, theselectivity for binary mixtures of CH4/CO2 and CH4/H2S was calculated. Th...
متن کاملControlling the formation of capillary bridges in binary liquid mixtures.
We study the formation of capillary bridges between micrometer-sized glass spheres immersed in a binary liquid mixture using bright field and confocal microscopy. The bridges form upon heating due to the preferential wetting of the hydrophilic glass surface by the water-rich phase. If the system is cooled below the demixing temperature, the bridges disappear within a few seconds by intermolecul...
