摘要：

Fixed bed adsorption dynamics of n-hexane from an air stream onto copper impregnated activated carbon were measured. The effect of air superficial velocity (0.7 cm/s and 1.7 cm/s), operation temperature (30 degrees C and 40 degrees C), and adsorbent copper loading (4.6 % and 13.8 %) on process performances was studied. Higher values of saturation adsorption capacity (0.190-0.254 g/g) were obtained at low level of air velocity and copper loading. A mathematical model including mass balance of adsorbed species and Langmuir monolayer adsorption, whose kinetic parameters were regressed based on experimental data, was adopted to predict the adsorption dynamics.
