以下本発明の実施のための具体的な実施例を図面を参照して説明する。
前記副生ガスから回収される二酸化炭素の透過度は下記の式1により計算される。
(実施例)
本発明で回収される二酸化炭素の分析はガスクロマトグラフィー分析により定性及び定量分析を行い、質量流量計(以下、MFCという)を使用して透過量を測定した。
図1で多孔性のシリコーン膜20として多孔性のシリコーンチューブ(厚さ2mm)を設置した後、副生ガスとして二酸化炭素50%、窒素50%の混合ガスを使用し、MFCを使用して2.5cc/secの流速で一定に反応器の内部で投入されるようにする。
水100gにナノセラミック0.5gを混合した後、超音波分散機を使用して十分に分散させた後、シリコーンチューブ(厚さ2mm)を浸した後、30分後に取り出して常温で3〜4時間の間乾燥させる。この過程を3回以上繰り返し行い、チューブの内部と外部に均等にコーティングされるようにする。
比較例1.
