a cylindrical shell ring extending along a longitudinal axis A-A that is vertical when the adsorber is in operation, the shell ring comprising a lower end cap, an upper end cap, and gas inlet/outlet nozzles; an external grid arranged in such a way as to be permeable to the gas and impermeable to the particles, the external grid extending along the vertical longitudinal axis; an internal grid arranged in such a way as to be permeable to the gas and impermeable to the particles, the internal grid extending along the vertical longitudinal axis; sealing means for sealing the lower part and the upper part of the internal grid and external grid, the internal grid and external grid between them forming an annular volume housing the adsorbent mass; an internal chamber located between the vertical longitudinal axis and the internal grid; an external chamber located between the external grid and the shell ring, the internal chamber and external chamber being intended for the circulation of the gas; the external grid being formed by a plurality of wires and a plurality of supports, the supports being mounted transversely to the wires, the supports and the wires being mounted secured to one another, the wires forming a plurality of longitudinal openings for the passage of the gas such that two adjacent wires define one of the longitudinal openings of the plurality, each longitudinal opening having a minimum opening width Lo for the passage of the gas, each wire having, in cross section, a maximum wire width Lf measured in the direction in which the supports extend; the external grid being arranged in such a way that the supports extend along the vertical longitudinal axis; and the external grid being arranged in such a way that the supports are positioned on the side of the external chamber and the wires on the side of the adsorbent mass. ### Claim 2 (depends on 1) The radial adsorber according to claim 1, wherein the external grid is cylindrical, the external grid and the shell ring is concentric. ### Claim 3 (depends on 1) The radial adsorber according to claim 1, wherein the external chamber defines an annular gas-distribution volume. ### Claim 4 (depends on 1) The radial adsorber according to claim 1, wherein the external chamber is configured to allow circulation of the gas over an entire periphery of the shell ring without encountering any obstacle. ### Claim 5 (depends on 1) The radial adsorber according to claim 1, wherein the external grid is configured to satisfy the relationship 0.05
