Description
(CO2捕捉材について)
用いるCO2捕捉材は特に拘らない。例えば、活性炭、ゼオライト、更には固体酸化物等が考えられる。またはアミン液等の液体も使用可能である。
(内燃機関について)
本発明が対象とする内燃機関は、CO2を発生するものであれば特に限定は無い。例えば、ガソリン車、ディーゼル車、天然ガス車等の内燃機関、更には建設機械や農業用機械及び船舶に使用される内燃機関等が考えられる。また、定置用エンジンも対象となりえる。(メタン化触媒について)
メタン化触媒としては、CO2と水素を反応させて以下のメタン化反応を促進できる触媒であれば特に拘らない。
メタン化触媒を、無機化合物の多孔質担体と、当該多孔質担体上に触媒活性成分として担持されたPt,Pd,Rh,Niから選ばれた少なくとも1種とを有し、前記多孔質担体が、Al,Ce, La,Ti,Zrから選ばれた少なくとも1種を含む触媒とすることでメタン化性能が高まる。メタン化触媒の多孔質担体として比表面積が高い酸化物を用いることでPt,Pd,Rh,Niが高分散化し、メタン化性能が高まる。特に多孔質担体としてAlを含む酸化物を使用すると安定して高いメタン化性能が得られる。本発明において用いる多孔質担体の比表面積は、30〜800m2/gの範囲が好ましく、特に50〜400m2/gの範囲が好ましい。
(H2の供給源について)
H2を発生させる方法にも特に拘らない。例えば、水素用のタンクを内燃機関に設置して、タンクからH2をメタン化触媒へ供給する事が考えられる。この場合、水素をガスのまま圧縮する、もしくは液化することでタンクにH2を積むことができる。
水を電気分解する方式として、例えば、アルカリ水電解型、固体高分子型等が考えられる。水を電気分解する為には、電気が必要となる。その場合、例えば内燃機関からのエンジン排ガスの熱を回収して電気を生じさせ、得られた電気を水電解に使用することが考えられる。
(熱回収方法)
内燃機関から排出される排ガスは400℃以上になりうる。従って排ガスの熱を利用して電気を得ることも有効である。その方法の一つとして、熱交換器、膨張機及び作動媒体の組み合わせを使用することが考えられる。
(熱電変換素子)
排ガスの熱を利用して電気を得る方法の一つとして、熱電変換素子の利用も考えられる。排ガス流路へ熱電変換素子を設置し、排ガスを熱電変換素子へ接触させることで、排ガスの熱を電気へと変換させ、電気を得ることができる。得られた電気は、水電解時の電気として使用する事ができる。
(燃焼触媒設置)
熱交換器あるいは熱電変換素子と、内燃機関に含まれるエンジンとの間に、排ガス中のH2、CO、炭化水素の少なくとも一種以上を燃焼する機能を有する触媒を設置することも考えられる。このような触媒を設置することで、排ガス中のH2、CO、炭化水素等が浄化されるのみならず、浄化反応により触媒後段の排ガス温度が上昇する。従って、熱交換器あるいは熱電変換素子による排熱の回収効率が更に高めることができる。
(大気中CO2回収)
CO2捕捉材へ大気を流入させることで、大気中のCO2を捕捉することもできる。この場合、CO2捕捉工程と、CO2脱離工程を組み合わせてCO2を回収する工程とすることもできる。更には、CO2捕捉材へある程度のCO2が捕捉された後には、新たなCO2捕捉材へ交換することも考えられる。
(材料の構成)
固体のCO2捕捉材及び、メタン化触媒に使用する多孔質担体、または活性成分は、基材上に担持させてもよい。基材としては従来から使用されてきたコージェライト、Si-Al-Oからなるセラミックス或いはステンレススチールなどの耐熱性金属基板などが適している。基材を用いる場合には、CO2捕捉性能及びメタン化性能を向上させる上で、材料の担持量は、基材1Lに対して10g以上300g以下であることが好ましい。10g以下であるとCO2捕捉性能及びメタン化性能が低下する。一方300g以上であると、基材がハニカム形状の場合にガス流路への目詰まりが発生し易くなる等の不具合が生じるようになる。
以下、本発明の実施例を説明する。
図1に、CO2捕捉材とメタン化触媒を組み合わせた実施例を示した。CO2捕捉材を二つ設置する。一方のCO2捕捉材へはエンジン排ガスを流通させ、CO2捕捉材のCO2回収量が飽和に達したら排ガスラインを切り替えて、もう一方のCO2捕捉材へ排ガスを流通させる構成としている。
図2には、CO2捕捉工程にあるCO2捕捉材の前段に熱交換器23を設置した実施例を示した。エンジン26としてガソリンエンジンを想定した。熱交換器23へは作動媒体を流通させる。熱交換器23を排ガスへ流入させることで、排ガスの熱を用いて、作動媒体を液体からガスへと変化させる。得られたガスを膨張機20へ導入することで発電させ電気を得る。膨張機20を通過した作動媒体ガスは凝縮機21へ導入され液体へと戻り、ポンプ22により循環する。
図3には、CO2捕捉工程にあるCO2捕捉材の前段に熱電変換素子33を設置した実施例を示した。排ガスを熱電変換素子へ流入させることで、排ガスの熱を電気に変換させる。得られた電気は、水電解装置28による水の電気分解に使用される。
図4には大気中のCO2を回収できる構成を示した。CO2捕捉材へ導入させるガスをエンジン排ガスでは無く、大気とした事以外は、図1と同様の構成とした。本構成にすることで大気中のCO2を回収することができ、大気中のCO2を削減することができる。
図5には、実施例2で示した構成を、ディーゼルエンジンを積んだ船舶へ適用した実施例を示した。エンジン34としてディーゼルエンジンを想定した。実施例2の場合と同様に、ディーゼルエンジン34から排出された排ガスの熱を回収し電気に変換する。得られた電気は、28の水電解装置に投入し水の電気分解に使用することで有効に利用できる。更に実施例5では、ディーゼル発電機35を備えている。ディーゼル発電機35から発生した電気Dを、水の電気分解へ使用することもできる。排熱を変換して得られた電気Aを併用することで、ディーゼル発電機35から得られた電気Dの水電解への使用量を効果的に減らすことができ、照明及び空調に用いる電気として使用することができる。
