Title (EN) IMPROVED ADSORBENT FOR REMOVAL OF AMMONIA FROM AIR STREAMS
(FR) ADSORBANT AMÉLIORÉ POUR ÉLIMINER L'AMMONIAC D'ÉCOULEMENTS D'AIR
Abstract: front page image
(EN)An improved air purification adsorbent is disclosed. The air purification adsorbent comprises titanium dioxide (TiO2) impregnated with zinc chloride (ZnC12). The adsorbent may be used in air purification systems for removing ammonia from air streams. The nanocrystalline (amorphous) structure of the adsorbent results in a higher density of surface defects, higher surface area, and higher reactivity which, when combined with the synergistic effect of ZnC12 and the nanocrystalline TiO2, provides a significantly longer breakthrough time of ammonia as compared with breakthrough time from unimpregnated nanocrystalline TiO2, the commercial (crystalline) TiO2 impregnated with ZnC12, pure ZnCL2, and other commercially available adsorbents of ammonia. Other embodiments are described and claimed.
(FR)L'invention concerne un adsorbant amélioré d'épuration d'air. L'adsorbant d'épuration d'air comprend du dioxyde de titane (TiO) imprégné de chlorure de zinc (ZnCl2). Cet adsorbant peut être utilisé dans des systèmes d'épuration d'air pour éliminer l'ammoniac présent dans des écoulements d'air. La structure nanocristalline (amorphe) de l'adsorbant permet d'obtenir une densité supérieure des défauts de surface, une surface utile supérieure et une réactivité supérieure, qui, combinées à l'effet synergique du ZnCl et du TiO nanocristallin, permettent d'obtenir un temps de pénétration de l'ammoniac considérablement plus long par rapport au temps de pénétration de TiO nanocristallin non imprégné, de TiO commercial (cristallin) imprégné de ZnCl, de ZnCl pur et d'autres adsorbants de l'ammoniac disponibles sur le marché. D'autres formes de réalisation sont décrites et revendiquées.
