On thermodynamics of methane + carbonaceous materials adsorption

International Journal of Heat and Mass Transfer, 2012
Abstract This study presents the theoretical frameworks for the thermodynamic quantities namely the heat of adsorption, specific heat capacity, entropy, and enthalpy for the adsorption of methane onto various carbonaceous materials. The proposed theoretical frameworks are developed from the rigor of thermodynamic property surfaces of a single ...

Comparative Study of Methane Adsorption on Graphite

Langmuir, 2008
To study methane adsorption on graphite in a wide range of coverages and temperatures, we compare experimental results with Monte Carlo simulations (MCSs) of the grand canonical ensemble (GCE) and mean-field approximation (MFA) of the lattice gas model (LGM).

Methane capacities of Zonguldak coals and the factors affecting methane adsorption

Mining Science and Technology, 1991
Abstract This study aimed to establish methane adsorption isotherms for coal samples taken from four different seams in Kozlu district, Zonguldak Coalfield, Turkey. The quantity of methane adsorbed by these samples, at different gas pressures up to 45 atm, was determined and the results were discussed in relation to the gas capacities of these coals.

The adsorption of methane on W(110)

Surface Science, 1997
The adsorption of CH4 and CD4 on W(110) was investigated. A monolayer of methane, probably containing 7 × 1014 molecules cm−2 is adsorbable at 25 K and desorbs near 50 K. Isothermal desorption is initially zero order but changes to first order after ∼58% of the layer has desorbed.

The adsorption of methane by tungsten (100)

Surface Science, 1971
The adsorption of methane by the (100) plane of tungsten has been studied using flash desorption and work function methods. It has been found that CH4 adsorbs to appreciable coverage as an undissociated molecular species at ∼ 110 K. The activation energy for first order desorption from this state is 6.9 kcal/mole (0.30 eV/molecule.

Adsorption Behavior of Methane on Kaolinite

Industrial & Engineering Chemistry Research, 2017
In this work, the adsorption behaviors of CH4 in slit-like kaolinite pores were investigated using the grand canonical Monte Carlo method. The research results show that the isosteric heat of adsorption of CH4 decreases with increasing pore size and that CH4 adsorption on kaolinite can be characterized as physical adsorption.
