A Monte Carlo simulation has been performed to study adsorption of CH{sub 4} on zeolites and the result are here presented for NaA and CaNaA zeolites. The adsorption isotherms of CH{sub 4} and the radial distribution of the adsorbed molecules have been obtained at four different temperatures in the pressure range 0 to 5 Mpa. The potential energy of adsorption has been calculated and the energy profile of a CH{sub 4} molecule along different axes in the zeolite cavity are discussed. High density storage of natural gas is essential for the efficient use of this gas as an alternative transportation fuel. One of the promising storage technologies is the adsorbed natural gas (ANG), in which the gas is adsorbed on highly microporous solids like zeolites or actived carbons. Structural as well as chemical properties of the porous adsorbents influence strongly the adsorption phenomenon, therefore, both experimental as theorical investigation are still necessary to select better solids for specific applications. {copyright} {ital 1996 American Institute of Physics.}
