Development of a Synthetic, Humidity Resistant, High Capacity Adsorbent for Collective Air Filters for Naval Vessels Phase 2.

摘要

Synthetic polymeric adsorbents, which were characterized by BET surface area and mercury intrusion volume, were evaluated for their potential as adsorbent media for collective air purification filters. The equilibrium water isotherms were determined for the synthetic adsorbents and ASC Whetlerite. These adsorbents were then screened for their dynamic capacities to adsorb the organic vapors diisopropyl fluorophosphate (DFP), dimethyl methylphosphonate (DMMP), and 2-chloroethyl isobutyl sulfide (CIS) from flowing air streams. The most promising adsorbents were more thoroughly evaluated using the bed depth service time technique to determine the kinetic saturation capacities using DFP, DMMP, CIS, methylene chloride, toluene, and o-xylene which provided a correlation of kinetic saturation capacity with the volatility or normal boiling point of the adsorptive . The DFP testing was done under both dry and highly humid conditions. In all of the dynamic testing, ASC Whetlerite was used as a control adsorbent.
