Abstract: Scrubber media for reactive gases, that can include but are not necessarily limited to hydrogen chloride (HCl), hydrogen sulfide (H2S), hydrogen fluoride (HF), and ammonia (NH3), can include reactive particles, potentially as small as nano-scale, that can optionally be suspended on macro-scale carrier particles. Reactive gases can be converted to non-volatile compounds by being passed through a bed of such scrubber media. Such scrubber media can be used to remove reactive gases from gas mixtures. Potential applications include differential absorption spectroscopy, air pollutant emission controls, and the like. Methods of preparing scrubber media are also described.
Abstract translation: 可以包括但不限于氯化氢（HCl），硫化氢（H 2 S），氟化氢（HF）和氨（NH 3））的反应性气体的洗涤介质可以包括可能小至纳米级的反应性颗粒， 可以任选地悬浮在大规模载体颗粒上。 反应性气体可以通过穿过这种洗涤介质的床而转化为不挥发性化合物。 这种洗涤介质可用于从气体混合物中除去反应性气体。 潜在应用包括差示吸收光谱，空气污染物排放控制等。 还描述了制备洗涤介质的方法。

Abstract: A method is disclosed which comprises maintaining a scrubber medium at a temperature in a range of -20°C to 85°C, the scrubber medium comprising reactive nanoparticles having first aerodynamic diameters of less than 250 nm that are adhered to carrier particles having second aerodynamic diameters in a range of 10 to 250 microns, the carrier particles being inert relative to one or more background compounds, the reactive nanoparticles comprising a solid-phase acid, the reactive nanoparticles being adhered to the carrier particles by one or more of van der Waals and electrostatic forces. In a further step, a gas mixture is contacted with the scrubber medium while the scrubber medium is maintained at the temperature, the gas mixture comprising a reactive compound and the one or more background compounds, the reactive compound comprising a gas-phase Lewis base, the contacting causing the reactive compound to react with the reactive nanoparticles to convert the reactive compound to one or more non-volatile salts or other non-volatile chemical compounds. An apparatus, a composition and a refreshing method are also disclosed.
