A packed adsorption system having excellent adsorption capacity, yet low flow resistance is disclosed. The packed adsorption system comprises a conventional adsorbent particle and a non-adsorbent filler having internal void structure. The disclosed adsorption system offers ease and flexibility in optimizing the adsorption capacity and flow resistance for the selected end-used applications by simply adjusting the relative level of adsorbent particle and a non-adsorbent filler in the adsorption system. The disclosed adsorption system provides at least about 30% reduction in pressure drop compared to a conventional adsorption system consisting entirely of the adsorbent, at an air flow rate of about 20 cm/sec, while affording no more than about 30% reduction in adsorption capacity compared to the convention adsorption system. When desired, the non-adsorbent filler may have an internal void fraction of greater than about 0.50. |
