Description
→7Ca3Al2(OH)12+xH2
この水素製造工程において、水の温度が、50〜100℃であり、マイエナイトと水酸化カルシウムのモル比が、1:9であることが好ましい。
この場合、カトイトの焼成温度は、300〜500℃であることが好ましい。
実施例1
図1に示す水素製造用試験装置を用いて本発明による継続的水素製造方法を実施した。
まず、容量1リットルの反応器(セパラブルフラスコ)にイオン交換水200mlを入れた。つぎに、アルミニウム粉体(商品名#150、ミナルコ社製)9gと水酸化カルシウム〔Ca(OH)2〕(和光純薬工業社製)12gを反応器に投入して撹拌した。水素ガスの生成が終了した後、イオン交換水をろ過し、ろ過された固形分を、温度70℃で、空気下で乾燥した。
→7Ca3Al2(OH)12+xH2
ここで、図3に示すXRD(X線解析測定、X-Ray Diffraction spectroscopy)の測定結果のパターンから、カトイト(Katoite)の構造に帰属するピークが示されており、カトイトが生成されていることが確認できた。
水素ガスの生成が終了した後、イオン交換水をろ過し、ろ過された固形分を、温度70℃で、空気下で乾燥した。
ここで、図4に示すXRD(X線解析測定)の測定結果のパターンから、マイエナイト(Mayenite)の構造に帰属するピークが示されており、マイエナイトが生成されていることが確認できた。
ついで、再生したマイエナイト6.1gおよび水酸化カルシウム2.9gを水素製造工程に戻した。
比較のために、上記実施例1の場合と同様の実験を行うが、実施例1の場合と異なる点は、マイエナイトおよび水酸化カルシウムの再生工程において、先に得られた固形分のカトイトの焼成を温度100℃で実施した点にある。その結果、焼成後の固形分は、図3に示すXRD(X線解析測定)の測定結果のパターンと同じもので、カトイトのままであることが確認され、マイエナイトは生じなかった。そのために、最後の循環工程を実施することはできなかった。
