Description
前記第1工程において水分及び二酸化炭素を吸収した触媒を加熱して炭化水素を生成する第2工程と、
を備えており、
前記触媒はLi 2 ZrO 3 又はLi 4 SiO 4 を主成分として含有した焼結多孔質体であることを特徴とする。
本発明の触媒は、Li2ZrO3又はLi4SiO4を主成分として含有した焼結多孔質体である。この焼結多孔質体は嵩密度が低い方が好ましい。また、本発明の触媒はこの焼結多孔質体を粉砕した粉末であってもよい。
次に、本発明の炭化水素の製造方法について、以下の実施例を用いて具体的に説明する。
各試料Xは、図2に示すように、直径8mm、厚さ1mmの円盤形状に形成した。試料1は、Li2ZrO3を主成分として含有した焼結多孔質体であり、嵩密度が2.53g/cm3である。試料2は、Li2ZrO3を主成分として含有した焼結多孔質体であり、嵩密度が3.78g/cm3である。図3(a)は試料1の表面を走査型電子顕微鏡(SEM)で撮影したSEM像であり,図3(b)は試料2の表面を走査型電子顕微鏡(SEM)で撮影したSEM像である。試料3は、Li4SiO4を主成分として含有した焼結多孔質体であり、嵩密度が1.57g/cm3である。図4は試料3の表面を走査型電子顕微鏡(SEM)で撮影したSEM像である。
(1)実施例では円盤形状の焼結多孔質体を試料(触媒)としたが、触媒は焼結多孔質体を粉砕した粉末であってもよい。
(2)実施例では触媒がLi2ZrO3又はLi4SiO4を主成分として含有した焼結多孔質体であったが、常温の大気中に放置した状態で大気中の水分及び二酸化炭素を吸収する触媒であればよい。
(3)実施例では試料(触媒)を真空中で加熱したが、第2工程において触媒を真空中で加熱しなくてもよい。
(4)実施例ではCH4を生成したが、他の炭化水素も生成し得る。
