Abstract: Purification material for removing a contaminant from an impure hydride gas comprising an adsorbent comprising a reduced metal oxide on a porous support and a desiccant. The porous support may be selected from the group consisting of activated carbon, alumina, silica, zeolite, silica alumina, titania, zirconia, and combinations thereof. The reduced metal oxide may comprise one or more metals selected from the group consisting of Group I alkali metals (lithium, sodium, potassium, rubidium, and cesium), Group II alkaline earth metals (magnesium, calcium, strontium, and barium), and transition metals (manganese, nickel, zinc, iron, molybdenum, tungsten, titanium, vanadium, cobalt, and rhodium). The desiccant may be selected from the group consisting of hygroscopic metal salts, zeolites, single metal oxides, mixed metal oxides, and combinations thereof.

Abstract: A gas adsorption composite a high density adsorbent including a high density layer having a first density of at least 0.3 g/cc; and a low density adsorbent having a low density layer having a second density of less than 0.3 g/cc, wherein the high density adsorbent is in substantially contiguous contact with the low density adsorbent and each of the high density adsorbent and the low density adsorbent has an adsorbent surface area of at least 500 m2/g. A pressure swing adsorption process for recovering a product gas from a feed gas, the process including supplying a pressure swing adsorption apparatus including a gas adsorption composite, feeding a feed gas into the pressure swing adsorption apparatus during a feed period not exceeding 100 seconds and recovering the product gas from the pressure swing adsorption apparatus.
