Description
M. J. den Exter, J. C. Jansen, H. van Bekkum, Studies in Surface Science and Catalysis vol.84, Ed. by J. Weitkamp et al., Elsevier(1994)1159-1166に記載のDDR型ゼオライトを製造する方法に従って、DDR型ゼオライト粉末を製造した。このDDR型ゼオライト粉末を水洗し、めのう乳鉢で粗粉砕した後、直径1mmジルコニア玉石を入れたボールミルを用いて16時間湿式粉砕した。粉砕後のスラリーを10μmの篩いに通して玉石と粗粒を取り除き、種結晶スラリーとした。この種結晶スラリーの一部を採取し、重量分析することで作製したスラリー中の種結晶濃度を確認した。
TiO2粉末150gとイオン交換水300gとを調合し、プロペラミキサーで10分攪拌してTiO2スラリーを得た。このTiO2スラリー中のTiO2粉末に対して、DDR型ゼオライト粉末の質量比が5%となるように、前記DDR種結晶スラリーをTiO2スラリーに加えて混合した。混合後のスラリーを10μmの篩いに通して粗粒を取り除き、更にプロペラミキサーで10分攪拌して種結晶含有層担持用スラリーを得た。
多孔質基材として、アルミナからなる多孔質の管状体(外径10mm、長さ1m、平均表面細孔径0.1μm)を用意した。これを水中で洗浄した後、図1に示すように、この多孔質基材1の一方の端部に、パイプ4を貫通させたゴム栓6とパイプ4に接続された真空ポンプ5とからなる吸引治具を装着するとともに、他方の端部をゴム栓7で密閉し、容器2内に満たされた前記種結晶含有層担持用スラリー3中に浸漬させて、真空ポンプ5により、多孔質基材1の内部を0.096MPaに減圧した。この状態を3秒間保持することにより、種結晶含有層担持用スラリー3を吸引濾過し、多孔質基材1の表面(外周面)にDDR型ゼオライト粉末(種結晶)とTiO2粉末とからなる種結晶含有層を担持させた。次いで、多孔質基材1を種結晶含有層担持用スラリー3から引き上げ、吸引したまましばらく放置した後、吸引を解除して、多孔質基材1から吸引治具を取り外した。その後、種結晶含有層を担持させた多孔質基材を、80℃の乾燥機内で乾燥し、800℃で1時間焼成することにより、種結晶含有層を多孔質基材に一体的に固定させて、種結晶含有層付き多孔質基材を得た。この種結晶含有層付き多孔質基材の表面と断面を走査型電子顕微鏡(SEM)で観察した。図2は種結晶含有層付き多孔質基材の表面の電子顕微鏡写真であり、図3は種結晶含有層付き多孔質基材の断面の電子顕微鏡写真である。
前記種結晶含有層付き多孔質基材を、四フッ化エチレン製で内筒付きのステンレス製耐圧容器へ入れ、この容器内に基材が完全に水没するようにゼオライト合成用原料溶液を注入した。ゼオライト合成用原料溶液の組成は、モル比で、SiO2:1−アダマンタンアミン:エチレンジアミン:H2O=1:0.06:0.5:80 とした。この容器を、種結晶含有層付き多孔質基材とゼオライト合成用原料溶液とを収容した状態で密閉して電気炉に入れ、160℃で10時間加熱して水熱合成を行い、多孔質基材の表面にゼオライト膜を成膜した。水熱合成後、多孔質基材を室温まで冷却し、電気炉から取り出してよく水洗し、乾燥させた。次いで、この多孔質基材を再び電気炉に入れ、大気中、650℃で12時間加熱することにより、膜中に残存する1−アダマンタンアミンとエチレンジアミンとを焼失除去し、DDR型ゼオライトからなるゼオライト膜を得た。こうしてゼオライト膜が成膜された多孔質基材の表面を、X線回折計で測定したところ、図4に示すように、基材を構成するアルミナの回折パターンと、DDR型ゼオライトの回折パターンが確認された。TiO2の回折パターンは確認されなかった。また、成膜後の基材表面及び表面近傍の断面を走査型電子顕微鏡で観察し、ゼオライトの結晶が基材表面にできていることを確認した。図5は成膜後における多孔質基材表面の電子顕微鏡写真であり、図6は成膜後における多孔質基材表面近傍断面の電子顕微鏡写真である。
図7に示すように、前記のようにして管状の多孔質基材1の表面に成膜されたゼオライト膜の両端部にシリコーンを薄く塗布して硬化させた後、Oリング11でシールされた状態で、ガス透過試験用チャンバー10内にセットした。混合ガス導入口12から多孔質基材1の内側に二酸化炭素(CO2)とメタン(CH4)を等モル混合した混合ガスを導入するとともに、スイープガス導入口13から多孔質基材1の外側にヘリウムガス(He)を流して、多孔質基材1とその表面のゼオライト膜を透過したガスを透過ガス回収口14から回収し、ガスクロマトグラフにてそのガス組成を分析した。その結果、回収されたガスにはCH4に対して7倍の濃度のCO2が含まれており、ゼオライト膜がガス分離膜として機能していることが確認された。
