TH8250B - Mixed porous charcoal - Google Patents

Abstract

What has been revealed is an improved aggregate selective membrane consisting of a finely porous absorbent backed by a porous substrate used to separate thin-component multi-gas mixtures. The intra-mixture is adsorbed within the porosity of the adsorbent and diffused through the membrane by surface flow resulting in a more permeate stream containing these elements. Well, this has been described as having a section that includes one or more oxidizing steps that increase the permeability and permeability of the membrane.
