Description
本願は、2011年07月25日に日本に出願された特願2011-162102号について優先権を主張し、その内容をここに援用する。
この高温ガスの顕熱を石炭の熱分解反応に活用し、ガス、タール・BTX(ベンゼン、トルエン、キシレン)、チャーをより多く製造するガス化炉として、ガス化炉の下室で石炭の部分酸化反応を行い、ガス化炉の上室で石炭の熱分解反応を行う二重二段構造の石炭熱分解ガス化炉が提案されている(特許文献1参照)。
特許文献1の方法においては、生成されたタールの軽質化を図るため、製品ガスの一部を水素ガスとしてリサイクルする設備が必要となっている。加えて、製品ガスの一部が消費されるため、最終生成物の生産量が減少してしまう。
また、製品ガスを調製する際、熱分解ガスとタールとが冷却器によって分離されるため、タールを回収する設備も必要となっている。さらに、熱分解ガスとタールとを分離する際に冷却が行われるため、熱分解ガスがもつ熱量のロスが生じて生成ガスの顕熱が有効に活用されず、製造効率が低下してしまう。
本発明の石炭ガスの製造方法は、内部に収容空間が形成された下部反応容器と、前記下部反応容器の上方に設けられた上部反応容器とを備え、前記上部反応容器は、前記下部反応容器の前記収容空間と連通するとともに上下方向に延びる貫通孔が形成された石炭ガス化反応炉を用いて、水素ガスおよび一酸化炭素ガスを含む石炭ガスの製造方法であって、
部分酸化反応により高温ガスを発生させるために、前記下部反応容器に第一の石炭、酸素および水蒸気を供給する工程と、
第二の石炭を熱分解させるために、前記上部反応容器に前記高温ガスを導入しながら前記第二の石炭を供給する工程と、
前記上部反応容器の出口から流出する石炭ガスの温度を1000℃以上に制御するために、前記上部反応容器に供給する前記第二の石炭の供給量の増減を調節する工程とを備える。
本発明のメタンの製造方法によれば、上述のタール含有量の少ない石炭ガスをメタン製造プロセスに適用することにより、従来よりも高い製造効率でメタンを製造できる。
本発明の石炭ガスの製造方法は、下部反応容器と上部反応容器とを備える特定の石炭ガス化反応炉を用い、前記下部反応容器に石炭(第一の石炭)、酸素および水蒸気を供給することによって、部分酸化反応により高温ガスを発生させる。前記上部反応容器に前記高温ガスを導入しながら新たに石炭(第二の石炭)を供給することによって、この新たに供給する石炭を熱分解させる。上記によって、水素ガスおよび一酸化炭素ガスを含む石炭ガスを製造する方法である。
かかる製造方法は、前記上部反応容器の出口から流出する石炭ガスの温度を1000℃以上に制御するために、前記上部反応容器に供給する前記第二の石炭の供給量の増減を調節することに特徴があり、その他の構成については、公知の石炭ガスの製造方法を適宜適用できる。
以下、本発明の石炭ガスの製造方法について、図1と図2を参照しながら説明する。
本実施形態の石炭ガス化システム1は、石炭ガス化反応炉4を用い、石炭を原料として水素ガスと一酸化炭素ガスを主成分とする石炭ガスを生成し、この石炭ガスから最終的にメタン、メタノール又はアンモニア等の製品を製造するプラント設備である。
石炭ガス化システム1は、石炭粉砕・乾燥設備2と、石炭供給設備3と、石炭ガス化反応炉4と、熱回収設備5と、チャー回収設備6と、シフト反応設備7と、ガス精製設備8と、化学合成設備9と、空気分離設備10とを備えている。
そこで、まず、石炭粉砕・乾燥設備2において、石炭は、外径がたとえば0.01mm以上0.15mm以下程度の粒状となるように粉砕される。さらに所定の水分含有量となるように乾燥された後に、石炭供給設備3に供給される。
なお、石炭粉砕・乾燥設備2の後から石炭ガス化反応炉4までは、乾燥された石炭中の水分含有量が変化しないように、粉砕された石炭は密閉された空間内を移動する。
続いて、石炭は、石炭ガス化反応炉4内に供給可能な石炭の状態にするために、石炭供給設備3内で搬送ガス等により所定の圧力まで昇圧され、その後、石炭ガス化反応炉4に搬送される。
一方で、空気分離設備10は、空気を圧縮して液化する。その液体となった空気から、沸点の違いにより、乾燥した酸素ガスや窒素ガス等を分離する。空気分離設備10で分離された酸素ガスは、石炭ガス化反応炉4に供給される。
図2は、本発明における石炭ガス化反応炉の一実施形態を示す縦断面図である。
本実施形態の石炭ガス化反応炉4は、内部に収容空間11aが形成された部分酸化部(下部反応容器)11と、部分酸化部11の上方(D方向においてD1)に設けられ、部分酸化部11の収容空間11aと連通し上下方向Dに延びる貫通孔12が形成された熱分解部(上部反応容器)13とを備えている。石炭ガス化反応炉4は、耐熱性のレンガ等で形成されている。
石炭ガス化反応炉4においては、部分酸化部11の下方(D方向においてD2)に、予熱部14が設けられている。部分酸化部11と予熱部14とは上下方向Dに連通していて、熱分解部13と部分酸化部11との接続部分、および部分酸化部11と予熱部14との接続部分は、これらが連なる部分より細くなるようにそれぞれ構成されている。
ガス化バーナー17は、石炭供給設備3、空気分離設備10、および後述する方法で水蒸気を発生する熱回収設備5に接続されていて、部分酸化部11に石炭、酸素ガスおよび水蒸気(以下これらをまとめて「炭素等」と称する。)を所定の割合で供給することができる。複数のガス化バーナー17は、部分酸化部11の内周面上において、相互に水平な位置となるように設置される。また、複数のガス化バーナー17の向きは、部分酸化部11の中心軸線C2に対して相互にねじれの位置となるように配置されている。また、ガス化バーナー17の向きは、斜め下方に向けられていても良い。
また、部分酸化部11の外周面には不図示の冷却手段が設けられていて、この冷却手段は、石炭の部分酸化反応により加熱される部分酸化部11の壁面を冷却することができる。
熱分解部13において、上下方向Dの中間部には熱分解部13に石炭を供給する複数の石炭ノズル18が設けられている。石炭ノズル18は、石炭供給設備3に接続されている。
なお、石炭ノズル18の数は制限されず、幾つでもよい。また、必要に応じて、たとえば、石炭ノズル18の下方(D方向においてD2側)に、熱分解部13に水蒸気を供給する水蒸気ノズルを設けてもよい。この水蒸気ノズルは、たとえば熱回収設備5に接続して設けることができる。
そして、端部12aには、端部12aから流出する石炭ガスの温度を測定する温度測定装置20が設けられている。
このとき、部分酸化部11内は、高温・高圧になっている。部分酸化部11内の温度と圧力は、部分酸化反応が良好に進行することから、温度を1300~1600℃とすることが好ましく、1300~1400℃とすることがより好ましく、圧力を2~4MPaとすることが好ましく、2~3MPaとすることがより好ましい。
この環境下で石炭が高温になり、熱分解してチャーと、タールおよび水蒸気等を含む揮発性ガスとが分離するとともに、石炭が燃焼(部分酸化反応)することにより、下記化学反応式(1)~(3)に示すように一酸化炭素ガス、二酸化炭素ガスおよび水素ガスと、スラグ(灰分)が発生する。
C+O2 → CO2 (2)
C+H2O → CO+H2 (3)
一方、部分酸化部11内で発生した高温ガス(一酸化炭素ガス、二酸化炭素ガス、水素ガス、水蒸気等を含むガス)、タール、チャー等は、旋回しながら部分酸化部11内を上昇し、部分酸化部11から移動して、熱分解部13内を上昇する。
熱分解部13に供給された新たな石炭中の炭素の一部は、熱分解部13内の二酸化炭素ガスと反応して、下記の化学反応式(4)により一酸化炭素ガスになる。
上述の石炭の熱分解反応、及び炭素の二酸化炭素ガスによるガス化反応は、吸熱反応であるため、部分酸化部11から上昇してくる高温ガスは冷却される。
石炭ガスの温度を1000℃以上に制御することにより、タール含有量の少ない石炭ガスを製造できる。石炭ガスの温度を1200℃以下に制御すると、石炭ガス化反応炉4が傷みにくくなり、石炭ガス化反応炉4の耐久性が向上する。
熱回収設備5では、熱分解部13から搬送された石炭ガスと水とを熱交換させることにより、水蒸気が生成される。この水蒸気は前述の石炭粉砕・乾燥設備2およびシフト反応設備7で用いる原料等の目的のために供給される。
熱回収設備5で冷却された石炭ガスは、熱回収設備5からチャー回収設備6に供給され、石炭ガスに含まれるチャーは、チャー回収設備6で回収される。
チャー回収設備6を通過した石炭ガスは、シフト反応設備7に供給される。そして、石炭ガス中の一酸化炭素ガスに対する水素ガスの比率を一定の値まで高めるために、シフト反応設備7中に水蒸気が供給される。下記の化学反応式(5)で示されるシフト反応により、石炭ガス中の一酸化炭素ガスが消費され、その代わりに水素ガスが発生する。
ガス精製設備8で精製された石炭ガスは化学合成設備9に供給され、種々の化学反応等により、メタンやメタノール等の製品が製造される。
タールは、瞬時に反応する石炭の初期熱分解反応で生成され、雰囲気ガス中のH2、H2O、CO2等により分解されて、消失する。したがって、石炭ガス中のタール含有量は、前記の生成と分解による消失とのバランスで定まる。分解反応による消失に影響する因子としては、雰囲気ガスの組成と、これに加えて反応速度に影響する温度が挙げられる。
一方で、石炭ガス化反応炉を用いた石炭ガスの製造において、タールの生成量は、原料として使用する石炭量に依存する。
これらのことから、本発明者らは、石炭ガス化反応炉を用いて石炭ガスを製造する際、上部反応容器に供給する石炭の供給量の増減を調節することにより、タールの生成量を制御すると共に、上部反応容器の出口から流出する石炭ガスの温度を、タールがほとんど生成されない1000℃以上に制御できることを見出し、本発明を完成するに至った。
本発明のメタンの製造方法は、上記本発明の石炭ガスの製造方法により製造される石炭ガスを、メタン化する方法である。その一実施形態として、図1に示す石炭ガス化システム1において、シフト反応プロセスとメタネーションプロセスとを組み合わせる方法が挙げられる。
上記本発明の石炭ガスの製造方法により製造される、タール含有量の少ない石炭ガスをメタン化することで、熱量のロスが低減され、従来よりも高い製造効率でメタンを製造できる。
石炭ガス化反応炉4において、端部12aには、図2に示すように、熱分解部13の出口(端部12a)から流出する石炭ガスの温度を測定する温度測定装置20を設けてメタンの製造を行った。
全ガス化バーナー17から部分酸化部11に供給する石炭、酸素ガスおよび水蒸気は、石炭500(kg/h)、酸素ガス300(Nm3/h)、水蒸気40(kg/h)で、それぞれ100時間供給した。
部分酸化部11内の温度と圧力は、温度1350℃、圧力2.45MPaとし、熱分解部13内の圧力を2.45MPaとし、ガス滞留時間を2秒間とした。
さらに、全石炭ノズル18から熱分解部13に供給する石炭は以下のように処理が行われた。
タール含有量は、熱分解部13の出口(端部12a)に設置したサンプリングノズルから生成石炭ガスの一部を所定量抜き出し、吸収液にタールを吸収させた後、当該吸収液を除去することにより測定した。
全石炭ノズル18から熱分解部13に供給する石炭を500(kg/h)で24時間供給することにより、石炭ガスの温度を800℃に制御した。
同様に、石炭を200(kg/h)で24時間供給することにより、石炭ガスの温度を1050℃程度に制御した。
同様に、石炭を150(kg/h)で24時間供給することにより、石炭ガスの温度を1150℃程度に制御した。
CO+3H2→ CH4+H2O
図3の結果から、石炭ガスの温度を800℃から1150℃に変化させたところ、石炭中の炭素のタールへの転化率(石炭ガスに含まれるタール含有量)が6.9質量%から0.3質量%へ顕著に減少していることが分かる。すなわち、本発明の石炭ガスの製造方法によれば、タール含有量の少ない石炭ガスを製造できることが確認できた。
一般的な気流層ガス化炉としては、現在商用化されている気流層ガス化炉として最も石炭ガス化効率が高いといわれている、Shellプロセスを参考に、石炭ガス化効率を80%(熱量ベース)として計算した。
本発明の製造方法においては、熱分解部13の出口(端部12a)から流出する石炭ガスの温度を1100℃に制御してメタン製造を行った。
図4中、「熱分解ガス化」は、石炭ガス化反応炉4の部分酸化部11における部分酸化と、熱分解部13における熱分解の両方を包含する。
化合物の下に示す数字は発熱量を示し、原料の石炭の発熱量を1.00とした際、たとえば本発明においては、熱分解ガス化の反応効率(η)が85%、すなわち15%分は熱量にロスが生じ、その73%分がCO+H2に転換され、残りの12%分がCH4に転換されたことを意味する。
次に、石炭ガスをメタン化する際、CO+H2(0.73)から、反応効率(η)74%で、CH4(0.54)が製造され、前記熱分解ガス化により得たCH4(0.12)と合わせて、石炭(1.00)からは全部でCH4(0.66)が製造された。
次に、石炭ガスをメタン化する際、CO+H2(0.80)から、反応効率(η)74%で、CH4(0.60)が製造され、石炭(1.00)からはCH4(0.60)が製造された。
