Abstract
The helium relative permeability of an alumina mesoporous pellet partially blocked by sorbed CCl4 has been studied on both sorption and desorption branches of the sorption isotherm. The plot of relative permeability (PR) against the amount of CCl4 sorbed (vs) is concave upwards; this is in contrast to the initially convex upwards curve reported previously for microporous Carbolac carbon containing paraffin sorbates, but in agreement with some preliminary computations based on a capillary-network model. Differences between the PR against vs plots for the sorption and desorption branches of the isotherm are not significant in relation to the repeatability of the results.
