The case 2 of the container 1 having a vertical axis X-X contains two adsorbent beds 3,4 in the form of sleeves retained by three cylindrical grates 5, 6, 7. The intermediate grate 6 is axially rigid and radially flexible while the innermost and outermost grates 5,7 are axially flexible and radially rigid. This enables the container and the adsorbent beds to support without damage the successive heating and cooling stages in the course of the adsorbent regeneration stages. Application to the purification of large amounts of air intended to be distilled.
