Experimental data for dynamic adsorption of ethyl acetate present in air using 5A and 13X molecular sieves are generated with variations of inlet adsorbate concentration, inlet velocity and bed diameter to bed length ratio to study their effects on the adsorber bed performance. Mathematical model based on Linear Driving Force approximation is validated with experimental data and simulated to understand effects of other pertinent parameters such as overall mass transfer coefficient, saturation capacity and bed to wall heat transfer coefficient. 13X molecular sieve with higher capacity than 5A shows closer to ideal adsorption behaviour. Mass transfer rate is controlled by pore diffusion.
