Flow of gases and vapours in a porous medium and its bearing on adsorption problems. Part I. - The steady state of flow

Abstract

A study has been made of the steady state of flow of He, Ne, A, Kr, H 2, O2, N2, NH3, CCl4 and SO2 through a bed of small nearly spherical synthetic analcite crystals. Flow rates, permeabilities, Knudsen and Poiseuille contributions to permeability and permeability constants have been determined and used to test the applicability of several equations of flow. Significant deviations from the behaviour suggested by these equations have been observed, especially for vapours. Pore properties and total surfaces have been determined using procedures based on steady state flow data.
