Analysis of Adsorbate–Adsorbate and Adsorbate–Adsorbent Interactions to Decode Isosteric Heats of Gas Adsorption

ChemPhysChem, 2015
AbstractA qualitative interpretation is proposed to interpret isosteric heats of adsorption by considering contributions from three general classes of interaction energy: fluid–fluid heat, fluid–solid heat, and fluid—high‐energy site (HES) heat. Multiple temperature adsorption isotherms are defined for nitrogen, T=(75, 77, 79) K, argon at T=(85, 87, 89)

Adsorbent storage of natural gas

Applied Energy, 1996
Abstract The natural-gas vehicle represents a cost-competitive, lower-emission alternative to the gasoline-fueled vehicle. The immediate challenge that confronts the natural-gas vehicle is extension of its driving range. This paper addresses the question of driving range by reviewing the storage technologies for natural gas. Technical comparisons are

ADSORBENT FILLED MEMBRANES FOR GAS SEPARATION

1993
The influence of specific adsorbents (zeolites and molecular sieve carbons) on the gas separation properties of polymeric membranes has been studied. Two main parameters, the pore size and the hydrophilic character of the zeolite, are investigated with respect to their effect on the overall membrane performance in the separation of carbon dioxide ...

Carbochromes as adsorbents in gas chromatography

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1973
1. The optimum conditions of modification of graphitized thermal carbon black with apiezon L and polydimethylsiloxane were determined. 2. Columns with modified carbon black possess high efficiency and selectivity in the selection of organic and organometallic compounds of various structures. 3.

Decomposition of Adsorbed Xylene on Adsorbent Using Nonthermal Plasma and Gas Circulation

2008 IEEE Industry Applications Society Annual Meeting, 2008
The xylene decomposition system which consists of adsorption process by adsorbents and adsorbed xylene decomposition process using nonthermal plasma with gas circulation is investigated. Two types of hydrophobic zeolite pellets are used as adsorbent.

The Structure of Gas Adsorbent Carbons

The Journal of Physical Chemistry, 1958
Irregularly shaped and layer-type pore strnctures have both been proposed for gas-adsorbent carbons. In an attempt to distinguish between these structures, the penetration by liquids with diberent molecular shapes into the pore systems of these carbons was studied.

Boron Nitride as a Selective Gas Adsorbent

Langmuir, 1994
A series of eight porous boron nitride materials with nitrogen/BET surface areas of 437-712 m[sup 2]/g have been produced using polymeric precursors varied by systematic synthesis modifications. All samples exhibit type I isotherms indicating that a majority of the porosity occurs in pores with radius less than 1.0 nm.

The first virial coefficient of an adsorbed gas

Advances in Colloid and Interface Science, 1976
Abstract Various approaches to the derivation of the first virial coefficient of an adsorbed gas by statistical mechanics are compared. Implicit assumptions are disentangled to show what is required to reconcile differences between them. Classical and quantum mechanical treatments are compared for the motion of adsorbed molecules normal to the ...

NMR Relaxation of Gas Adsorbed in Microporous Material

The Journal of Physical Chemistry Letters
NMR relaxometry has been widely applied to characterize fluid confined in porous media because of its versatility, chemical selectivity, and noninvasive nature. Here we extend its usage to gas adsorbed in microporous materials by establishing a new quantitative model based on the molecular level NMR relaxation mechanism revealed by the molecular ...
