Abstract
Description
CH3OH + 0.5O2 → CO2 + 2H2 (1)
で表されるように、メタノールが酸化し、水素ガスと二酸化炭素ガスが生成する。このメタノールの酸化反応は、発熱反応であるため、系内の温度が上昇する。
CH3OH → CO + 2H2 (2)
で表されるように、一酸化炭素ガスと水素ガスに分解したり、式(3):
CH3OH + H2O → CO2 + 3H2 (3)
で表されるように、二酸化炭素ガスと水素ガスに分解したりする。これらの分解反応は、いずれも吸熱反応であることから、前記酸化反応で発生した熱の一部が打ち消される。その結果、系内の温度は、前記酸化反応のみが起こる場合の温度と対比して、幾分かは低い温度となる。また、これらの反応以外にも、式(4):
CO + H2O → CO2 + H2 (4)
で表されるシフト反応が起こると考えられている。
〔酸素ガス停止時間の比率〕
=〔(酸素ガスの供給を停止する時間)÷(1周期に要する時間)〕×100 (I)
で表される酸素ガス停止時間の比率は、酸化銅/酸化アルミニウム触媒の触媒活性を充分に回復させるとともに水素ガスを効率よく製造する観点から、30%以下であることが好ましい。例えば、前記1周期に要する時間を10秒間としたとき、酸素含有ガスを供給する時間が7秒間以上であり、酸素含有ガスの供給を停止する時間が3秒間以下であることが好ましい。
長さ20cm、内径2.3cmの反応器内に、酸化銅/酸化アルミニウム触媒[アルドリッチ社製、酸化銅(CuO)と酸化アルミニウム(Al2O3)との質量比〔酸化銅(CuO)/酸化アルミニウム(Al2O3)〕:12/88]を充填した後、水素ガスを含む窒素ガスを約10時間反応器内に導入することにより、酸化銅/酸化アルミニウム触媒を賦活させた。
実施例1において、空気を標準状態で2.2L/分の流量で10分間通気した後、当該空気の通気を60秒間停止する操作を1周期として周期的に繰り返したこと以外は、実施例1と同様の操作を行なった。そのとき、式(I)で表される酸素ガス停止時間の比率は、約9%であった。
その結果を表2に示す。
実施例1において、空気を標準状態で2.0L/分の一定流量で供給したこと以外は、実施例1と同様にして反応を行なった。その結果を表3に示す。
Claims (5)
- 酸素含有ガスを供給しながら触媒の存在下でメタノールと水を接触させることによって反応ガスを製造し、当該反応ガスから水素ガスを分離することによって水素ガスを製造する方法であって、前記触媒として酸化銅/酸化アルミニウム触媒を用い、酸素含有ガスの供給を一時的に停止することを特徴とする水素ガスの製造方法。
- 酸化銅/酸化アルミニウム触媒をあらかじめ還元させた後に使用する請求項1に記載の水素ガスの製造方法。
- 酸素含有ガスの供給の開始から当該酸素含有ガスの供給の停止に至るまでの時間を10秒〜10分間に制御する請求項1または2に記載の水素ガスの製造方法。
- 酸素含有ガスの供給を停止させる時間が3〜60秒間である請求項1〜3のいずれかに記載の水素ガスの製造方法。
- 酸素含有ガスの供給を開始する時点から、当該酸素含有ガスの供給を停止させた後、次の酸素含有ガスの供給を開始するまでの1周期に要する時間に対する酸素含有ガスの供給を停止させる時間の比率が30%以下である請求項1〜4のいずれかに記載の水素ガスの製造方法。
