The dynamic adsorption behavior of granular activated carbon and 5Å molecular sieve adsorbers on xenon adsorption has been studied. The goal was to design and fabricate an absorber pack bed with optimized conditions. To measure the xenon in the column output contains adsorbent, a chromatography apparatus equipped with a thermal conductivity detector was used. The effect of isotherm gas flow rate and temperature variations at a constant flow velocity of gas on the dynamic adsorption process were studied. Variables such as range of the mass transfer zone and range of the unused bed have been calculated using breakthrough curves. The Langmuir model was used to predict the required absorber quantity and proper adsorption process by calculating the adsorption capacity of the absorbent. The results have shown an appropriate consistency with the model outputs, and a better adsorption performance was approved for the granular activated carbon absorber.
