Abstract:

Understanding the adsorption of water vapor onto activated carbons is important for designing processes to remove dilute contaminants from humid gas streams, such as providing protection against chemical warfare agents CWAs, or against toxic industrial compounds TICs used in a terrorist chemical attack. Water vapor isotherms for Calgon BPL granular activated carbon GAC, military ASZM-TEDA GAC, electrospun activated carbon nanofibers ACnF, Calgon Zorflex activated carbon cloth, and Novoloid-based activated carbon fiber cloth ACFC are presented. Of particular interest are the ACFC isotherms, which exhibit an unusually high degree of hydrophobicity. The ACFC isotherms also show a correlation between water vapor adsorption hysteresis and the level of activation. Water vapor isotherm models from the literature are compared.
