Abstract

The desorption characteristics of methane from a Maxsorb II specimen of activated carbon were measured over the temperature range of 281–343 Kand at pressures up to 1.2 MPa. The technique of measuring the dead volume in the measurement system using helium calibration has also been perfected. The desorption data were fitted to two isotherm models proposed by To´th and Dubinin–Astakhov with an accuracy better than 0.004 g g-1. The data are compared with those from adsorption and correlations are developed by combining the adsorption and desorption data. The Henry’s law coefficients and their relations with extrapolated isosteric heat of adsorption at saturation are analyzed.
