1. An adsorber, comprising an adsorbent bed structure containing an adsorbent bed of at least one elementary composite structure that comprises adsorbent particles in a polymer matrix, wherein the adsorber is adapted and configured to separate gas through adsorption and the adsorbent bed has a bed packing, ρbed, defined as a volume occupied by the at least one elementary composite structure, Vecs, divided by a volume of the adsorbent bed structure Vbed, where ρbed is greater than 0.60,
wherein the at least one elementary composite polymer/adsorbent structure comprises a plurality of elementary composite polymer/adsorbent structures configured as beads or extrudates having an average major dimension Dmaj and an average minor dimension Dmin, wherein a ratio of Dmaj:Dmin is in the range of 1:1 to less than 20:1,
wherein the adsorbent bed is configured as a radial adsorbent bed, the adsorber further comprising a cylindrical pressure vessel having an inlet and an outlet, a first annular porous grid concentrically disposed within the cylindrical pressure vessel, a second annular porous grid concentrically disposed within the first annular porous grid wherein a first annulus is formed between an inner surface of the cylindrical pressure vessel and an outer surface of the annular porous grid and a second annulus is formed between an inner surface of the first annular porous grid and an outer surface of the second annular porous grid, a gas-tight annular floor sealing a bottom of the second annulus in gas-tight fashion, and a gas-tight annular ceiling sealing a top of the second annulus in gas-tight fashion, wherein the adsorbent bed structure is comprised of the first and second porous annular grids, the gas-tight annular floor, and the gas-tight annular ceiling, and wherein the adsorber is adapted and configured such that:
feed gas comprising a first component and a second component that is fed to the inlet of the cylindrical pressure vessel flows into the first annulus, through the first annular porous grid, and into the plurality of elementary composite polymer/adsorbent structures configured as beads or extrudates where a first component of the feed gas is preferentially adsorbed by the at least one elementary composite structure compared to a second component of the feed gas; and
a gas enriched in the second component and deficient in the first component compared to the feed gas flows through the second annular porous grid and out of the outlet of the cylindrical pressure vessel.
