CA 2715519

A method of preparing a gas separation membrane system and the gas separation membrane system itself, wherein the method includes applying a layer of a gas-selective material to a porous substrate followed by heat-treating thereof in an inert gaseous atmosphere and then polishing and repeating these steps to thereby provide the gas separation membrane system or a structure that may suitably be used in a gas separation membrane system.

Cette invention se rapporte à un procédé de préparation d'un système de membrane de séparation de gaz et au système de membrane de séparation de gaz lui-même, le procédé incluant l'application d'une couche de matériau sélectif vis-à-vis d'un gaz sur un substrat poreux, puis le traitement thermique de celle-ci sous une atmosphère gazeuse inerte et une opération de polissage. Ces étapes sont répétées pour fournir de ce fait le système de membrane de séparation de gaz ou une structure qui peut être utilisée de manière appropriée dans un système de membrane de séparation de gaz.
