図6に図示されたような二重管構造の水素生産反応器を製造した。内部管としては銅(Cu)管を使い、外部管としては石英(Quartz)管を使った。銅管の外壁および内壁に窒化ホウ素(BN)を含むペイントをコーティングした後、熱処理してコーティング層を形成した。
銅管の外面に窒化ホウ素(BN)を含むペイントをコーティングする時、ペイントに触媒をさらに混合してコーティングしたことを除いては製造例1と同一にして水素生産反応器を製造した。触媒としてはアルミナ(Al2O3)にルテニウム(Ru)を担持したものを使った。
銅管にコーティング層を形成しない点を除き、製造例1と同様の水素生産反応器を製造した。
製造例1、製造例2および比較製造例による水素生産反応器でアンモニア分解反応を生じさせて水素を生産しながら、アンモニアの転換率を測定した。その結果は図8の通りである。これを参照すると、製造例2による水素生産反応器はアンモニア分解反応に活性を有する触媒が銅管の外壁に含まれているので、アンモニアの転換率が40%に達することが分かる。
