MONTE-CARLO SIMULATION ON THE ADSORPTION PROPERTIES OF METHANE IN ZEOLITE-L

The adsorption of methane in K+ ion exchanged zeolite L has been studi ed using grand canonical ensemble Monte Carlo simulation. Average numb er of molecules per unit cell, number density of molecules in zeolite, distribution of molecules per unit cell, average potential per sorbat e molecule, and isosteric heats of adsorption were calculated, and the se results were compared with experimental results. The simulation res ults agreed fairly well with experimental ones. All methane molecules were located in the main channel, and the average potential of sorbate molecule was almost constant regardless of average number of molecule s per unit cell and the amounts sorbed in zeolite.
