Title
(EN) PROCESS FOR SEPARATION OF AMMONIA GAS AND A SOLID ADSORBENT COMPOSITION
(FR) PROCEDE DE SEPARATION DE GAZ AMMONIAC ET COMPOSITION ADSORBANTE SOLIDE ASSOCIEE
Abstract
(EN)
The present invention is a process for ammonia gas separation from gas mixtures by a solid copper (I)-containing adsorbent. The process enables an effective and selective separation of ammonia gas from gas mixtures. Additionally it enables the efficient release of adsorbed ammonia by regeneration as well as the ammonia recovery as a pure gas for reuse. The present invention also comprises the adsorbent composition for use in selective adsorption of ammonia and the manufacturing of the adsorbent.

Procédé permettant de séparer du gaz ammoniac de mélanges gazeux à l'aide d'un adsorbant solide contenant un composé cuivreux. Ledit procédé permet une séparation efficace et sélective du gaz ammoniac de mélanges gazeux. De plus, il permet la libération efficace du gaz ammoniac adsorbé par régénération, ainsi que la récupération du gaz ammoniac en tant que gaz pur en vue de sa réutilisation. La présente invention concerne également la composition adsorbante destinée à être utilisée pour l'adsorption sélective du gaz ammoniac et la fabrication dudit adsorbant.
