Abstract

L'invention concerne un procédé de fractionnement d'un mélange gazeux contenant au moins deux constituants. Dans ce procédé on utilise au moins deux couches comprenant chacune un tamis moléculaire qui a la propriété d'adsorber préférentiellement l'un des constituants à une pression relativement élevée. On tire du système le constituant le moins facilement adsorbable sous forme de produit et le constituant adsorbé se désorbe lors d'une diminution de pression dans le tamis moléculaire. Application à la séparation des gaz.The invention relates to a process for fractionating a gas mixture containing at least two components. In this process, at least two layers are used, each comprising a molecular sieve which has the property of preferentially adsorbing one of the constituents at a relatively high pressure. The less readily adsorbable component is withdrawn from the system as a product and the adsorbed component is desorbed upon a decrease in pressure in the molecular sieve. Application to the separation of gases.
