ABSTRACT:
For drying a gaseous stream in thermally regenerable cyclically connected adsorbers wherein the gaseous stream contains components polymerizable under regeneration conditions, the bed is subdivided into several layers having different adsorbents. The first layer consists essentially of an adsorbent, e.g., zeolite type 4A, having a higher adsorption capacity for polymerizable compounds than the second layer, e.g., zeolite type 3A but with the second layer adsorbent being mechanically more stable than the first layer adsorbent.
