摘要: Nitrogen oxides and low molecular weight hydrocarbons are removed from air by subjecting the air to a temperature swing adsorption process using as the adsorbent a composite zeolite product containing both zeolite type A and zeolite type X. The composite zeolite product is prepared by crystallizing a sodium ion- or sodium ion- and potassium ion-containing alumina-silica hydrogel under conditions which result in the production of a zeolitic composite which contains both zeolite type A and zeolite type X crystal domains. In a preferred embodiment, calcium ions constitute a substantial number of the composite's exchangeable cations and the type X portion of the composite zeolite product has a silicon-to-aluminum atomic ratio in the range of 0.9 to less than 1.15. The nitrogen oxide- and hydrocarbon-selective adsorbent can be incorporated into an atmospheric air prepurification plant downstream of a water vapor-selective adsorbent and a carbon dioxide-selective adsorbent.

摘要: The present invention provides for a thermal swing adsorption process for the removal of trace impurities such as oxides of nitrogen and hydrocarbons from air prior to its separation by cryogenic distillation. The process may utilize three adsorbent layers, the first primarily removes water; the second primarily removes carbon dioxide; and the third layer is a composite adsorbent layer which removes the oxides of nitrogen and hydrocarbons from the air stream. Another embodiment employs a two layer adsorbent system to remove the impurities. Additionally, a single layer of composite adsorbent may be used to remove water, carbon dioxide, oxides of nitrogen, and hydrocarbons from the air stream.
