Abstract
【解決手段】 装置外部から紫外光を照射することにより、光触媒の存在下でCO2を水またはメタノールと反応させてCO2を固定化するCO2の固定化反応装置であって、反応槽12の上部開口部が光透過性材料11で封止されており、CO2ガス導入口13及び反応生成ガス排出口14を、液面と接触しない反応槽12の側壁の上部に備えたことを特徴とするCO2の固定化反応装置。
【選択図】 図1
Description
CO2ガス導入口と生成ガス排出口とを備えたステンレス製の耐圧容器(内径:40mm、高さ:160mm、容量200ml)に、純水20mlを入れ、これにイオウを担持した可視光応答型酸化チタン光触媒1gを懸濁させた。CO2ガス供給ラインの先端には、テフロン(登録商標)チューブ製の吹き込みラインを接続し、その先端が液面により下になるように設置した。反応槽の上部に、パッキンを介して厚さ約30mmの石英ガラス製光透過性材料を設置し、さらにその上にパッキンを介してステンレス製上蓋を設置し、全体をボルトで固定することにより、図1に示す固定化反応装置を製作した。
純水の変わりにメタノールを使用し、光触媒としてパラジウム1%を担持した酸化チタン光触媒を使用した以外は、実施例1と同様の方法により、室温で21日間、CO2の光固定化反応を行った。反応後、生成ガス排出口の調整バルブを開けて生成ガスを取り出し、これをガスクロマトグラフィー(GC)により同定・定量した。その結果を表1に示した。
