Description
Summary:Binary and ternary equilibrium adsorption data of methane, ethane, and ethylene on titanosilicate ETS-10 zeolites are reported at temperatures of 280 K and 325 K and pressures of 350 kPa and 700 kPa. The experimental data are modeled using the ideal adsorbed solution theory (IAST) in conjunction with the pure isotherms of Toth, Unilan, and Virial. The fit of this model to these data is satisfactory. Values of the relative adsorptivity calculated from the data and the IAST fits of the data show that the separation of methane from ethane or ethylene is extremely feasible at any conditions. Also, the separation of ethane from ethylene is highly favorable on ETS-10, particularly at low temperature. The removal of methane or ethane from the ternary mixture methane + ethane + ethylene is extremely easy at any operating conditions.
