摘要
Equilibrium isotherms for the adsorption of ethylene, propane, propylene, and carbon dioxide on 13X zeolite have been obtained at 279, 293, and 308 K, in the pressure range 0-100 kPa. Experimental data were fitted to Langmuir, Prausnitz, and BET equations, showing the best results with Prausnitz isotherm. Binary adsorption isotherms for all binary systems were also obtained at 293 K and the same pressure range. Some displacement effects were observed for several systems at the adsorbed phase. Thus, propane is displaced by propylene for increasing pressures, showing a maximum in its individual adsorption isotherms.
