Abstract
Cette invention concerne des membranes composites semi-perméables renfermant un matériau adsorbant poreux déposé sur un substrat poreux et servant à la séparation de mélanges gazeux. Le procédé de séparation repose sur l'adsorption d'un ou de plusieurs constituants primaires par les pores du matériau adsorbant et la diffusion par écoulement de surface à travers la membrane pour la production d'un perméat enrichi d'un ou de plusieurs de constituants primaires. Cette invention concerne également des méthodes de fabrication desdites membranes composites.
