Description
本発明における流体分離膜(以下、単に「分離膜」という場合がある)は、緻密層を有し、当該緻密層が実質的な流体の分離層として機能する分離膜である。
ただし、構造周期が大きくて小角散乱が観測できない場合がある。その場合はX線コンピュータ断層撮影(X線CT)によって構造周期を得る。具体的には、X線CTによって撮影した三次元画像をフーリエ変換した後に、その二次元スペクトルの円環平均を取り、一次元スペクトルを得る。その一次元スペクトルにおけるピークトップの位置に対応する特性波長を求め、その逆数として構造周期を算出する。
本発明の流体分離膜は、16℃大気圧において液体または固体である単環式または二環式の芳香族化合物(以下、単に「芳香族化合物」という場合がある)が合計2~10,000ppm吸着し、かつ水が10~250,000ppm吸着していることを特徴とする。
本発明の流体分離膜は、一例として、緻密層からなる分離層を有する流体分離膜を準備する工程と、該流体分離膜に芳香族化合物及び水を吸着させる工程を有する製造方法により製造できる。
芳香族化合物および水を吸着する前の流体分離膜は、市販のものを用いてもよいが、一例として下記工程1~3により作製することができる。この例は、緻密層及び支持体が炭素からなる流体分離膜の例である。以下、炭素からなる緻密層を「緻密炭素層」と呼び、炭素からなる支持体を「多孔質炭素支持体」と呼ぶ。ただし、本発明において流体分離膜の製造方法は以下に限定されるものではない。
工程1は、多孔質炭素支持体の前駆体となる樹脂(以下、「支持体前駆体樹脂」ということがある)を含む成形体を500℃以上2,400℃以下で炭化することで多孔質炭素支持体を得る工程である。
後述する工程2で多孔質炭素支持体に炭化可能樹脂層を形成する前に、炭化可能樹脂層との接着性を向上させるため、多孔質炭素支持体に表面処理を行ってもよい。このような表面処理としては、酸化処理や薬液コート処理が挙げられる。酸化処理としては、硝酸や硫酸などによる薬液酸化法,電解酸化法,気相酸化法が挙げられる。また、薬液コート処理としては、多孔質炭素支持体へのプライマーやサイジング剤の付与が挙げられる。
工程2は、工程1で準備した多孔質炭素支持体上に、緻密炭素層の前駆体となる炭化可能樹脂層を形成する工程である。多孔質炭素支持体と緻密炭素層をそれぞれ別の工程で作製することにより、緻密炭素層の厚みを任意に設定できる。そのため、例えば、緻密炭素層の厚みを薄くすることによって流体の透過速度を向上させることができる等、分離膜構造の設計が容易になる。
工程2で作製した、炭化可能樹脂層が形成された多孔質炭素支持体(以下、「多孔質炭素支持体/炭化可能樹脂層複合体」という)は、炭化処理(工程3)の前に不融化処理を行ってもよい。不融化処理の方法は限定されず、前述の多孔質炭素支持体の前駆体の不融化処理に準じる。
工程3は、工程2で作製され、必要に応じてさらに不融化処理を行った多孔質炭素支持体/炭化可能樹脂層複合体を加熱して、炭化可能樹脂層を炭化し、緻密炭素層を形成する工程である。
次に、このようにして準備した流体分離膜に、芳香族化合物及び水を吸着させる。本工程は連続工程で行っても、バッチ工程で行ってもよい。
(芳香族化合物および水の吸着量の測定)
加熱発生ガス分析法(TPD-MS法)により定量した。具体的手順を以下に示す。まず、流体分離膜表面を軽く布でふき取った。次いで、温度コントローラ付き加熱装置と質量分析装置を直結し、ヘリウム雰囲気中で加熱した際、加熱時に流体分離膜から発生する気体の濃度を分析し、流体分離膜のトルエン、ベンゼン及び水の吸着量を得た。温度プログラムは、まず室温から80℃まで10℃/分で昇温し(ステップ1)、80℃で30分保持し(ステップ2)、さらに180℃まで10℃/分で昇温し(ステップ3)、180℃で30分保持した(ステップ)際の発生量の総量をトルエン、ベンゼン及び水の吸着量とした。また、ステップ1及び2において発生する芳香族化合物気体のみから求められる芳香族化合物の吸着量をAa(ppm)とし、ステップ3及び4で発生する芳香族化合物気体の量のみから求められる芳香族化合物の吸着量をBa(ppm)とし、同様に、ステップ1及び2において発生する水蒸気のみから求められる水の吸着量をAw(ppm)とし、ステップ3及び4で発生する水蒸気の量のみから求められる水の吸着量をBw(ppm)とし、Ba/Aa及びBw/Awを算出した。
本発明の流体分離膜は、加熱発生ガス分析法(TPD-MS法)にて、室温から300℃まで10℃/分で昇温しながらトルエン、ベンゼン、水の発生量をオンライン測定した際、温度変化に対する発生量をプロットした曲線のピーク数を確認した。なお、流体分離膜表面上に存在する液膜、液滴の影響を除外するため、流体分離膜が目視で濡れていた場合には、測定は流体分離膜表面をウェス等で拭いてから行うった。
長さ10cmの流体分離膜を10本束ねて外径φ6mm、肉厚1mmのステンレス製のケーシング内に収容し、束ねた流体分離膜の端をエポキシ樹脂系接着剤でケーシング内面に固定するとともにケーシングの両端を封止して、流体分離膜モジュールを作製し、ガス透過速度を測定した。
なお、ガス分離係数は開始直後及び100時間経過後にそれぞれ測定した。さらに、後者を前者で除することにより、100時間使用後の分離係数保持率を求めた。
70gのポリサイエンス社製ポリアクリロニトリル(MW15万)と70gのシグマ・アルドリッチ社製ポリビニルピロリドン(MW4万)、及び、溶媒として400gの和研薬製ジメチルスルホキシド(DMSO)をセパラブルフラスコに投入し、2.5時間攪拌および還流を行いながら135℃で溶液を調製した。
実施例1と同様の手法で流体分離膜を得た。さらに、関東化学社製トルエン250mLと純水250mLとを混合し、50℃に加熱して、その蒸気に24時間曝露した。
実施例1と同様の手法で流体分離膜を得た。さらに、関東化学社製ベンゼン250mLと純水250mLとを混合し、50℃に加熱して、その蒸気に24時間曝露した。
実施例1と同様の手法で流体分離膜を得た。さらに、関東化学社製トルエン250mLと純水250mLとを混合し、50℃に加熱して、その蒸気に4時間曝露した。
実施例1と同様の手法で流体分離膜を得た。その後、吸着処理は行わず、トルエン、ベンゼン及び水の吸着量、加熱発生量曲線のピーク数確認及びガス分離係数の測定を実施した。
実施例1と同様の手法で流体分離膜を得た。さらに、水600mLを50℃に加熱し、その蒸気に24時間曝露した。
