ABSTRACT:
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).
