This invention provides a DDR type zeolite membrane, characterized in that it is formed as a membrane on a substrate and its main component is silica, and that each single gas permeance at room temperature and 100°C are different, respectively among at least two types of gases selected from a group consisting of carbon dioxide (CO2), hydrogen (H2), oxygen (O2), nitrogen (N2), methane (CH4), normal butane (n-C4H10) , isobutane (i-C4H10) , sulfur hexafluoride (SF6) , ethane (C2H6) , ethylene (C2H4) , propane (C3H8) , propylene (C3H6) , carbon monoxide (CO), and nitrogen monoxide (NO).
La présente invention concerne un film zéolitique de type DDR caractérisé par le fait qu'il est formé sur un substrat. Il comprend du silice comme composant principal et présente par rapport à au moins deux gaz sélectionnés dans le groupe constitué de dioxyde de carbone (CO2), hydrogène (H2), oxygène (O2), azote (N2), méthane (CH4), n-butane (n-C4H10), isobutane (I-C4H10), hexafluor de soufre (SF6), éthane (C2H6), éthylène (C2H4), propane (C3H8), propylène (C3H6), monoxyde de carbone (CO) et monoxyde d'azote (NO), différentes perméabilités entre des gaz simples respectifs à température ambiante et à 100<0> C.
