Study of Methane Storage and Adsorption Equilibria in Multi-Walled Carbon Nanotubes [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2008
Adsorbed natural gas has various advantages and is relatively more economical than liquefaction and compression. Carbon nanotubes can be introduced as a new candidate for natural gas storage.

First principles study of the adsorption of C60 on Si(111) [PDF]

, 2000
The adsorption of C60 on Si(111) has been studied by means of first-principles density functional calculations. A 2x2 adatom surface reconstruction was used to simulate the terraces of the 7x7 reconstruction.

A Study of the Removal of Minor Amounts of HS from Natural Gas by Activated Carbon

Adsorption Science & Technology, 2002
Studies have been made of the removal of minor amounts of H 2 S from natural gas by activated carbon. The surface alkalinity of the carbon had a considerable effect on the H 2 S capacity, although this was not permanent.

Improper Estimation of Thermodynamic Parameters in Adsorption Studies with Distribution Coefficient K D (q e/C e) or Freundlich Constant (K F): Considerations from the Derivation of Dimensionless Thermodynamic Equilibrium Constant and Suggestions

Adsorption Science & Technology, 2022
Adsorption processes often include three important components: kinetics, isotherm, and thermodynamics. In the study of solid–liquid adsorption, “standard” thermodynamic equilibrium constant K Eq o ; dimensionless) plays an essential role in accurately ...
