Water Adsorption with Hysteresis Effect onto Microporous Activated Carbon Fabrics - PREPRINT

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 C2A1 GAC, electrospun activated carbon nanofibers (ACnF), Calgon Zorflex(TM) activated carbon cloth, and Novaloid-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 hysterisis and the level of activation. Water vapor isotherm models from the literature are compared.
