An adsorbent and a process are disclosed for drying gases in a pressure swingndryer. The adsorbent comprises a pre-formed alumina particle with a thin layer ofncolloidal silica dispersed on the surface of the pre-formed alumina particle. Surprisinglynthe thin layer of colloidal silica does not interfere with the drying properties of the pre-formednalumina particle, while significantly improving the physical properties of the pre-formednalumina particle. |
