Multifunctional Adsorbent Structures for Air Purification

Abstract

Commercial fire escape masks (FEMs) use packed bed filters to remove gaseous and vaporous toxic components in the event of building fires to provide at least 15 min of respiratory protection. Packed bed filters incur a high pressure drop and commercial masks are unable to remove environmental (fire) or process (reaction and adsorption) heats. The aim of this work is to propose and optimise a novel multifunctional monolithic adsorbent filter for application within an FEM, providing a step change improvement above current commercial packed bed designs by (i) reducing inhalation burden, (ii) maintaining or improving the capacity and kinetic performance to adsorbed or react with harmful gases and (iii) extend the capability of the filter to remove heat.
