MIXED-GAS ADSORPTION AND VACUUM DESORPTION OF CARBON DIOXIDE ON MOLECULAR SIEVE - TERMODYNAMIC AND RATE BEHAVIOR

A mathematical model for adsorption and desorption processes is given with experimental data. The data verify the model proposed and are used to determine several important operating and potential design parameters for the adsorption of CO2 on 5A molecular sieve. The fundamental data reported include isotherm data for CO2 adsorption on Linde 5A molecular sieve. Empirically determined coefficients for mass transfer during adsorption and desorption cycles are given together with pressure drop coefficients for low pressures (during vacuum desorption). These empirical coefficients are compared in a numerical simulation for the small experimental bed. © 1968, American Chemical Society. All rights reserved.
