Water Adsorption Equilibria on Microporous Carbons

Abstract

Water vapor adsorption and desorption equilibria was measured for BPL, ASC, ASC-TEDA, and CWS carbons, a polymeric beaded carbon and a foreign military filter carbon. The effect of temperature was considered over the range of 15-35 C. An isotherm expression was developed to describe capillary condensation on a particle with a disperse pore size distribution. This expression was fit to the measured data in order to compare the pore size distributions of the sample studies. A second isotherm expression was proposed based on a modification of the Antoine equation. This equation proved useful in obtaining a best fit correlation to the adsorption data.
