Description
内径21mm、長さ500mmの石英ガラス管の中央部に、直径2mmの孔を9箇所あけた目皿を取り付けた反応器に、ガラスウールを詰め、炭酸リチウム(純度99.99%、高純度炭酸リチウム PLC−4N、パシフィックリチウム株式会社製)を1.01g充填した。反応器の上部と下部には、ガスの供給管・排気管が取り付けられており、また、熱電対が目皿付近まで到達するように保護管が取り付けられている。反応器下部のガス供給管から、3%水素含有窒素ガス(ジャパンファインプロダクツ株式会社製)を200ml/min導入し、外部加熱により700℃まで加熱した。700℃になったことを確認した後、雰囲気ガスを流しながら常圧にて42時間反応を行った。
実施例1において、雰囲気ガスを3%水素含有窒素から窒素に変更した以外は、実施例1と同様に実験を行った。24時間反応を行ったが、転化率は12%で実施例1と比較して極めて反応速度が遅かった。転化率の推移を図1に示した。
