図1は、モノリス型分離膜構造体100の斜視図である。図2は、図1のA−A断面図である。図3は、図2のB−B断面図である。
まず、多孔質材料を含む坏土を用いて、複数の貫通孔THを有する基材211の成形体を形成する。多孔質材料は、アルミナを主成分とする骨材と、ガラスフリットを主成分とする無機結合材とを含有することが好ましい。基材211の成形体を形成する方法としては、真空押出成形機を用いた押出成形法のほかプレス成型法や鋳込み成型法を用いることができる。
本実施形態において、モノリス型分離膜構造体100は、基材211と、第1濾過層212とを備える。第1濾過層212は、アルミナを主成分とする骨材と、チタニアを主成分とする無機結合材とを含有する。第1濾過層212の厚みは、150μm未満である。
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。
1.サンプルNo.1〜3
以下のようにして、サンプルNo.1〜3に係るモノリス型分離膜構造体を作製した。
第2濾過層の骨材としてアルミナを用いて焼成温度を1250℃とした以外は上記サンプルNo.1〜3と同様の工程にてサンプルNo.4,5を作製した。
第1濾過層の無機結合材としてチタニアを用いた以外は上記サンプルNo.1〜3と同様の工程にてサンプルNo.6〜11を作製した。ただし、サンプルNo.11に係る基材のサイズは、直径180mm、長さ1500mmであった。
第2濾過層を作製しなかった以外は上記サンプルNo.1〜3と同様の工程にてサンプルNo.12〜15を作製した。
各サンプルを透水装置に組み込み、ポンプにて水を送液し、この際の透水量と透過圧力を測定した。表1中の透水量は1atmの圧力にて水が透過する速度を示している。また、水流束とは、第1濾過層における単位面積当たりの透水量であり、透水量を第1濾過層の表面積で割ることで算出される。
サンプルNo.1〜3,7〜10のそれぞれから切り出した試験片を圧力容器に組み込み、PH1.8の薬剤硫酸に浸漬した状態で200℃にて3時間加熱した。その後、試験片を取り出してよく洗浄した。次に、試験片を圧力容器に組み込み、100ppmの次亜塩素酸水溶液に試験片を浸漬した状態で再度200℃にて3時間加熱した。この硫酸及び次亜塩素酸による2回の薬液負荷を1サイクルとする薬液処理を、第1支持層のビッカース硬度が20を下回るまで繰り返し行った。ビッカース硬度が20を下回ったときの薬液処理のサイクル数を表1に示す。
