Abstract:

The use of activated carbon fabrics ACFs that are desorbed electrothermally, also known as the Joule effect, is explored as a potential method to create a regenerating chemical warfare agent CWA filter. Electrical resistance vs. temperature measurements are presented for kynol-based ACF and compared with results for ACFs produced from other substrates. Adsorption and desorption results for dimethyl-methylphoshonate DMMP demonstrate that organophosphate compounds can be effectively desorbed from ACF. Chloroethane and propane are used to simulate the behavior of low-molecular-weight CWAs. Results for these more weakly adsorbed simulants indicate that a system that could indefinitely reject HCN without impregnants may be feasible. Planned efforts to advance this technology by both experimentation and modeling are discussed.
