Popis:	Pure component and multicomponent equilibrium adsorption data are reported for the adsorption of the light n-alkanes on Linde 5A and 13X pellets in the temperature range 275-350K and at pressures up to 1.732 MPa but primarily at a pressure of 345 kPa. The intrinsic Henry constants and heats of adsorption are extracted from the data using virial isotherm techniques. The experimental K 0 values for 13X are in excellent agreement with theoretical quantum mechanical calculations. For zeolite 5A, predictions of theoretical pure component, binary, and ternary profiles employing the Ruthven isotherm using intrinsic Henry constants are satisfactory. For 13X zeolite, profile predictions using the Ruthven isotherm require that the intrinsic Henry constant be increased by on average 212% to adequately fit the data. This increase is attributed to the increase in the heat of sorption with loading for these systems
