Popis:	1. The adsorption of methane on NaX zeolite in the subcritical and supercritical regions was studied, and it was found that the adsorption isoteres are linear in the range of pressures from ∼0.1 Pa to ∼20 MPa and in the range of temperatures from 120 to 600°K. The adsorption isosteres, interrupted at the methane saturated vapor pressure line, subsequently continue linearly in the supercritical region. 2. The first adsorbed molecules at relatively low temperatures are adsorbed in deep potential wells, which naturally realizes the Langmuir model of adsorption in zeolite.
