Abstract
Description
(1)セラミックファイバーからなる支持体と酸化金属触媒とを含む酸化金属触媒担持体であって、
前記セラミックファイバーの平均繊維径は、1μm〜20μmの範囲にあり、
前記セラミックファイバーは絡み合って撓んでおり、
前記支持体の嵩密度は、0.10g/cm3〜0.50g/cm3の範囲にあり、
前記酸化金属触媒は、前記セラミックファイバーの表面上に粒径1μm以下の微粒子として均一に存在する、酸化金属触媒担持体。
前記燃焼気化部は、燃焼管と、形状が前記燃焼管の内壁に対応し、前記燃焼管の内部に配置されている、前記(1)又は(2)に記載の酸化金属触媒担持体とを備える、全量有機炭素計。
次に、実施例に基づいて本発明をさらに詳細に説明するが、本発明は以下の実施例等によって何ら限定されるものではない。
市販のウール状のセラミックファイバー(イソライト工業株式会社製、商品名;イソウール1260バルク、平均繊維径;2.8μm、繊維長;短繊維(1〜2mm程度)〜250mm)を、ミルで粉砕して、ファイバーの平均繊維長を500μmにした。粉砕したセラミックファイバーをTOC計の燃焼気化部の燃焼管の内面に対応するように、天然石英ガラス管(内径12mm)に、嵩密度0.18g/cm3になるように充填して成形し、1,000℃で1時間加熱して焼成し、直径12mm、高さ90mmの円柱状の支持体を得た。得られたセラミックファイバーの支持体に、塩化白金酸水溶液を用いて、常法に従って白金を担持して、酸化金属触媒担持体1を得た。製造工程の概略を図1に示す。酸化金属触媒担持体1のSEM写真を図2(5,000倍)及び図3(1,500倍)に示す。図2では、セラミックファイバーの表面上に100個以上の酸化金属触媒の微粒子が外周方向に均一に存在している領域が観測される。酸化金属触媒の微粒子の平均粒子径は1μmであった。図3では、セラミックファイバーが絡み合って撓んでいることが分かる。嵩密度は0.2g/cm3前後、開気孔率90%以上であり、非常にガス透過性の高い素材であった。
また、初回、3000回目、5000回目のNDIR検出器の電圧のグラフ(相対値)を図8に示す。5000回目でも波形が崩れず、測定に支障がないことが分かる。
(比較例1)
市販のウール状のセラミックファイバー(イソライト工業株式会社製、商品名;イソウール1260バルク、平均繊維径;2.8μm、繊維長;短繊維(1〜2mm程度)〜250mm)に、塩化白金酸水溶液を用いて、常法に従って白金を担持した。白金を担持したウール状のセラミックファイバーをTOC計の燃焼気化部の燃焼管に挿入して、酸化金属触媒担持体2を得た。製造工程の概略を図1に示す。酸化金属触媒担持体2のSEM写真を図4(5,000倍)及び図5(1,500倍)に示す。図4では、セラミックファイバーの上の酸化金属触媒は不均一に分布していることが観測される。図5では、セラミックファイバーが絡み合っておらず、セラミックファイバーは直線状で撓んでいないことが分かる。
