Simulation of methane adsorption on A-zeolites

AIP Conference Proceedings, 1996
A Monte Carlo simulation has been performed to study adsorption of CH4 on zeolites and the result are here presented for NaA and CaNaA zeolites. The adsorption isotherms of CH4 and the radial distribution of the adsorbed molecules have been obtained at four different temperatures in the pressure range 0 to 5 Mpa.

Methane adsorption on Rh/Al2O3

Journal of Molecular Catalysis A: Chemical, 1998
Abstract The rates of CH 4 adsorption on a supported Rh catalyst after different treatments of the surface were measured by means of a temporal-analysis-of-products (TAP) reactor. The catalyst was kept in a well-defined state during adsorption experiments by using a very small pulse size. CH 4 adsorbs on reduced sites.

Methane adsorption in PIM-1

Adsorption, 2010
We report the results of Grand Canonical Monte Carlo (GCMC) simulations of methane adsorption in a prototypical polymer of intrinsic microporosity, PIM-1. Polymer chains were represented with a united-atom model, with Lennard-Jones parameters obtained from the TraPPE potential.

Adsorption of methane + ethane and methane + carbon monoxide on molecular sieves

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1981
Experimental sorption isotherms are obtained for methane, ethane and carbon monoxide in three molecular sieves (two zeolitic and one carbon). Pressures from a few millibar absolute to as high as 30 bar are covered. Sorption isotherms for the binary mixtures methane + ethane and methane + carbon monoxide in the same sorbents are also obtained at 298 K ...

Methane and Carbon Dioxide Adsorption on Illite

Energy & Fuels, 2016
The adsorption of CH4 and CO2 onto illitic clay was investigated at the temperatures 298, 313, 328, 358, and 423 K (25, 40, 55, 85, and 150 °C) over a range of pressures up to 50 MPa using grand canonical Monte Carlo (GCMC) simulations. Our simulation results showed spontaneous and exothermic adsorption behavior of illite for CH4 and CO2 with enthalpy ...

Dissociative and molecular adsorption of methane on rhodium

Surface Science, 1987
Although chemisorption of methane is a classical example of activated chemisorption, the mechanism for its dissociation on metals is not well understood. On rhodium, vibrational excitation has been postulated as playing a role, but has not been found in experiments.

Adsorption of methane on porous metal carboxylates

Journal of Industrial and Engineering Chemistry, 2009
Abstract Porous metal carboxylates such as MIL-101 (Cr-terephthalate), MIL-100-Cr (Cr-trimesate) and MIL-100-Fe (Fe-trimesate) with very high porosity have been tested as potential adsorbents for methane storage materials. The MIL-101 shows one of the highest adsorption capacities for methane.

The adsorption of methane on polycrystalline iron films

Surface Science, 1983
Abstract The adsorption of methane on evaporated iron films at 77 K is discussed by means of adsorption isotherms, changes in resistance and work function. The thermal desorption spectrum shows only one peak at about 130 K. There is no adsorption of methane at 273 K. The results are compared with those found for methane adsorption on nickel films.

Multifractal Characterization of Methane Adsorption in Coal Pores

Langmuir
The present research on the complex and heterogeneous characterization of methane (CH4) adsorption in coal pores has not yet been revealed. In this article, the multifractal theory is employed to explore the complexity and heterogeneity of CH4 adsorption in coal pores. The results show that the generalized fractal dimension D(q) follows a monotonically

Molecular Simulations of Methane Adsorption in Silicalite

Molecular Simulation, 1991
Abstract Grand canonical ensemble Monte Carlo (GCMC) simulatios of methane in the zeolite silicalite have been used to predict adsorption isotherms over a wide range of occupancies at several temperatures. The zeolite has been modeled using a detailed atomistic description, as have the methane molecules.
