Abstract: A filtration device including a fluid-impermeable housing having a gas inlet and outlet, and containing within the housing first filter media particles of an extended surface area substrate and containing at least one metal impregnant, and second filter media particles of an extended surface area zirconium hydroxide substrate. The device may be used in atmospheres containing various harmful gases, and may provide particularly useful improvements in NOx breakthrough times compared to a device containing only the first filter media particles or only the second filter media particles.

Abstract: A filtration device including a fluid-impermeable housing having a gas inlet and outlet, and containing within the housing first filter media particles of an extended surface area substrate and containing at least one metal impregnant, and second filter media particles of an extended surface area zirconium hydroxide substrate and zinc (hydr)oxide. The device may be used in atmospheres containing various harmful gases, and may provide particularly useful improvements in NOx breakthrough times compared to a device containing only the first filter media particles or only the second filter media particles.
Abstract translation: 一种过滤装置，包括具有气体入口和出口的流体不可渗透的壳体，并且在壳体内容纳有延伸的表面积基底的第一过滤介质颗粒，并且包含至少一种金属浸渍剂，以及延伸表面积锆的第二过滤介质颗粒 氢氧化物底物和氧化锌（hydr）。 该装置可以在含有各种有害气体的气氛中使用，并且与仅含有第一过滤介质颗粒或仅包含第二过滤介质颗粒的装置相比，可提供特别有用的NOx穿透时间改进。
