GAS ADSORPTION TREE

A gas adsorption tree includes a track of multiple, different porous descending levels each pair of the levels defining therebetween an angle of declination. The tree further includes a single exit disposed at a distal end of the track. Finally, the tree includes multiple, different gas adsorbent spheres each traversing each of the levels of the track towards the single exit according to gravitational motivation. In one aspect of the embodiment, the porous descending levels are circuits which when combined form a spiral track. In an alternative aspect of the embodiment, the porous descending levels are ramps such that an ascending edge of each lower positioned one of the ramps in the tree extends beyond a descending edge of an adjacent upper positioned one of the ramps in the tree.
