Description
図1は、分離膜構造体10の構成を示す断面図である。分離膜構造体10は、少なくともメタン分子(以下、「メタン」と略称する。)と窒素分子(以下、「窒素」と略称する。)を含有する混合ガス中の窒素を選択的に透過させる。分離膜構造体10は、多孔質支持体20及びゼオライト膜30を備える。
分離膜構造体10の製造方法について説明する。
まず、押出成形法、プレス成形法あるいは鋳込み成形法などを用いて、基体21の原料を所望の形状に成形することによって基体21の成形体を形成する。次に、基体21の成形体を焼成(例えば、900℃〜1450℃)して基体21を形成する。
多孔質支持体20の表面にゼオライト膜30を形成する。ゼオライト膜30は、骨格構造に応じた従来既知の手法で形成することができる。
分離膜構造体10を用いた窒素濃度低減方法について説明する。
本実施形態に係る分離膜構造体10は、多孔質支持体20と、多孔質支持体20上に形成され長径DLと短径DSを有する細孔30aを含むゼオライト膜30とを備える。短径DSに対する長径DLの比は、1より大きい。短径DSは、0.30nm以上かつ0.35nm以下である。
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。
