More Information
Summary:The present disclosure described compositions which may be effective in removing contaminants from a gas stream such as nitrous oxides. The composition may include a sorbent which contains triethylenediamine and a metal including copper, zinc, or a combination thereof. Methods of making such a composition are also described, along with devices which use the composition to remove contaminants from fluid streams, particularly in vehicle tunnels and parking garages. La présente invention concerne des compositions qui peuvent être efficaces pour éliminer dans un flux de gaz des polluants tels que des oxydes nitreux. La composition peut comprendre un sorbant qui contient de la triéthylènediamine et un métal comprenant le cuivre, le zinc ou une combinaison de ceux-ci. L'invention concerne également des procédés pour produire une telle composition, ainsi que des dispositifs qui utilisent la composition pour éliminer des polluants de flux de fluide, en particulier dans des tunnels empruntés par des véhicules et des garages de stationnement.
