Popis: Several commercially available adsorbents that show promise for the separation of CH4 from N2 including different activated carbons, desiccants, and zeolites were evaluated using single component adsorption isotherms of pure methane and nitrogen that were measured at 303 K for pressures of up to 10 atm using the gravimetric method. Following the screening, the adsorption of binary gas mixtures composed of methane and nitrogen were studied at 303 K and two different pressures on the adsorbents with the highest capacity for CH4 of each of the activated carbons, desiccants, and zeolites. These selected adsorbents included commercial zeolite 13X (Siliporite Nitroxy Pro from CECA Arkema Group), activated carbon (Xtrusorb A754 from Calgon Carbon Corp.), and silica gel (SG-B127 from Grace & Co). A concentration pulse chromatographic method was used to determine the pure component CH4 and N2 Henry’s Law constants, heats of adsorption, and the experimental binary adsorption isotherms for the three selected adsorbe...
