Adsorption of Methane and Argon Mixture on Planar Graphite

We report on the adsorption equilibration data for Methane and Argon mixture (50:50 mixture) on planar graphite. Time evolution of the composition of a gaseous mixture of Argon and Methane in the vapor phase during adsorption on graphite sample over broad range of initial pressures at a fixed temperature was measured. A correlation between the final compositions as a function initial starting pressure of the gas mixture will be presented and discussed.
