Mixed-Gas Adsorption

چکیده
The prediction of multicomponent adsorption equilibria from single-component data is one of the most challenging and important problems in adsorption. The chief obstacle to progress is a scarcity of accurate and consistent experimental data o®er a wide range of temperature and loading for testing theories. Se®eral binaries and one ternary system ( ) on two types of zeolites silicalite and faujasite were studied in a combination calorimeter-®olumetric apparatus. Acti®ity coefficients and excess functions for enthalpy, free energy, and entropy were extracted from the binary data using a three-constant equation to represent nonidealities. The successful correlation of binary excess functions with pure-component properties for type I isotherms on zeolites is a first step toward predicting multicomponent adsorption from single-gas adsorption and a major ad®ancement o®er the theory of ideal adsorbed solutions.

Study on the Adsorption, Diffusion and Permeation Selectivity of Shale Gas in Organics
As kerogen is the main organic component in shale, the adsorption capacity, diffusion and permeability of the gas in kerogen plays an important role in shale gas production. Based on the molecular model of type II kerogen, an organic nanoporous structure was established. The Grand Canonical Monte Carlo (GCMC) and Molecular Dynamics (MD) methods were used to study the adsorption and diffusion ca...

In this work, molecular dynamics (MD) was performed to simulate the dynamic processes of 1:4 acetone/nitrogen permeating through different Al2O3 membranes by Materials Studio 2.2 software package. Three modeling systems were constructed applying different modeling box lengths as well as different hollow size and texture of Al2O3 membranes to compare different permeation behaviors. In each syste...

1. Introduction The combination of chromatographic method and moment analysis of the response peaks is one of the useful techniques to study adsorption equilibrium and adsorption rate [1]. Perturbation chromatography with the mixed multi component adsorbate gas carrier (two adsorbates) has been applied to several studies on adsorption [2][3]. In this work, perturbation chromatography with multi...
متن کاملEffect of Surfactant Adsorption on the Wettability Alteration of Gas-Bearing Shales
Water loss in low permeability reservoirs during hydraulic fracturing well completions typically results in a decrease in natural gas production due to capillary trapping near the fractures. Shale gas reservoirs, however, have shown a trend of improved gas production with increased loss of completion fluids to the shale. This nonintuitive relationship between water imbibition and enhanced gas p...
متن کاملSelective gas adsorption and fluorescence sensing response of a Zn(ii) metal-organic framework constructed by a mixed-ligand strategy.
By means of a mixed-ligand strategy, a novel bi-functional metal-organic framework, [H2N(CH3)2]·Zn(NDC)(atz)·H2O (NDC = 2,6-naphthalenedicarboxylic acid, Hatz = 1H-tetrazol-5-amine), was synthesized, which displays a three-dimensional two-fold interpenetrated framework. Owing to the introduction of two different functional organic ligands, this complex exhibits bi-functional properties, i.e., s...
متن کاملMixed ( Ar ) n ( N 2 ) m van der Waals clusters created by pick - up technique
A comparison of the adsorption efficiencies for Ar atoms on large (N2)m (m = 1320−10600) clusters and N2 molecules on large (Ar)n (n = 7900−17000) clusters has been investigated by the pick-up technique. Using mass spectroscopy, it has been shown that mixed (Ar)n(N2)m clusters can be created either by depositing Ar atoms from buffer gas on the surface of (N2)m clusters or by depositing N2 molec...
