The adsorbent of the present invention has a pore volume / medium volume of at least about 0.12 cc pore volume / cc medium, a specific heat capacity based on pore volume less than about 2.9 J / cc pore volume, and a surface air velocity of about 4.0 in H 2 O / ft media and is placed in the adsorbent concentrator system. The extruded honeycomb sorbent media has a cell density greater than about 200 cells per square inch (cspi), an open area of at least about 50%, an activated carbon content of at least about 50 wt% based on the total weight, Has a pressure drop less than about 4.0 inH 2 O / ft media at surface air velocity. |
