Abstract
Abstract A dense pack gas adsorbent means comprising at least one particulate gas adsorbent having a particulate size distribution in which the largest small particles are leass than one-third (1/3) the size of the smallest large particle and sixty percent (60%) of the adsorbent particles having a size greater than sixty (60) mesh, said adsorbent particle oriented to provide a packing density grater than one hundred and thirty percent (130%) of the particle's apparent density.
