The selectivity of various adsorbents in relation to mixtures of methane (trace component) and nitrogen was studied earlier by the method of frontal chromatography and it was found that BAU microporous active carbon has the highest selectivity. Since data on the mechanism of the process and on the coefficient of mass transfer are needed for organization of a process for effective removal of methane from nitrogen, the authors have studied the dynamics of methane adsorption from mixtures with nitrogen in the region of methane concentrations corresponding to the linear region of the adsorption isotherm. The experiments were carried out at various overall flow rates of the mixtures at T = 197 K in columns 0.94, 1, and 1.94 m long and 0.03 m in diameter. The columns were packed with BAU carbon of grain size 2.5-5.0 x 10 U m.
