Description
図1は、リアクタの基本的な構成を説明するための図であり、本発明のリアクタの一実施形態は、図1のリアクタ100の構成に基づいて、図2に示すような改良を加えた構成を有する。図1において、垂直に交わるX軸、Y軸、Z軸は、図示の通り、各々、反応流体の流通方向及びそれに垂直な水平方向、並びに、鉛直方向として規定している。
反応流体導入部120及び反応流体排出部122は、各々、円柱周面状に湾曲した側壁を有する部分円筒形状を有し、これらと積層された伝熱壁110との間に、反応流体の導入及び排出用の空間が各々形成される。積層された伝熱壁110の反応流体導入部120側末端及び反応流体排出部122側末端において、熱媒体流路群220が配される層状空間は、閉鎖板116によって閉止されるが、反応用流路群210が配される層状空間は解放されるように孔210aが形成される。従って、反応用流路群210は、孔210aを介して、反応流体導入部120及び反応流体排出部122の内側の空間と連通する。
また、熱媒体導入部130及び熱媒体排出部132は、側部に鉛直方向の開口を有する中空構造を有し、リアクタ100への熱媒体の供給及び回収が、熱媒体導入部130及び熱媒体排出部132の中空部を介して行われる。このために、熱媒体導入部130及び熱媒体排出部132が設けられる側の側壁板114は、一層おきに両端において欠損するように短く設定されて、熱媒体流路群220の空間が解放される孔220aが両端に形成される。従って、熱媒体流路群220は、孔220aを介して熱媒体導入部130及び熱媒体排出部132の中空部と連通する。

本発明においては、熱媒体流路群220に供給される熱媒体として、リアクタの構成素材を腐食させない気体物質が好適に使用できる。熱媒体として気体物質を使用する構成は、液体媒体を使用する場合と比較して、取り扱いが容易である。
次に、本発明のリアクタにおける反応用流路群210及び熱媒体流路群220の具体的な構成について、図2を参照して説明する。図2(a)は、1つの熱媒体流路群220を示し、図2(b)は、1つの反応用流路群210を示し、図2(c)は触媒構造体300が装填された反応用流路群210を示す。図2においては、熱媒体流路群220と反応用流路群210との区別を理解し易くするために、図1の伝熱壁110を伝熱壁110a及び伝熱壁110bに区別して記載する。又、図2(b)においては、反応用流路群210への触媒構造体300の装填を説明するために、1つの触媒構造体300を記載する。図2におけるX軸、Y軸、Z軸の規定は、図1と同様であり、この規定は、以下に説明する図4~図6においても同様である。
上述の熱媒体流路群220の構成は、図1(a)に記載される構成と同様である。
このような本体部310は、隔壁112と同じ長さの薄板材に対して、垂直に屈曲する曲げ加工を行うことによって得られ、例えば、薄板材の一側から曲げ加工を繰り返して上記各部を順次形成することによって、図2(b)のように折り畳まれたコルゲート形状に成形される。この際、頂部322及び底部324の幅の合計が反応用流路212の幅に実質的に等しくなるように、頂部322及び底部324の数及び幅(Y軸方向)を設定し、側壁部326及び区画壁部328の幅が反応用流路212の高さ(Z軸方向)に実質的に等しくなるように構成することによって、装填された触媒構造体300が反応用流路212内に密接固定される。
このように触媒構造体300の本体部310に連通部を設けることによって、各反応用流路212における部分流路間の相互流通及び反応用流路212と外部との流通が局所的に生じるが、連通部以外の部分においては、部分流路は各々独立する。本体部310の間隙330の位置及び流通方向(X軸方向)の長さは、隔壁112の間隙230と実質的に一致するように設けられる。つまり、本体部310の連通部は、パーティションの連通部350に対応して、部分流路及び間隙230(パーティションの連通部)を相互に連通させるように配置されるので、本体部310の連通部とパーティションの連通部350とが反応用流路群210を真っ直ぐに貫くように配される。
図4は、本発明に係るリアクタの連通部に関する第1変形例を説明するための図である。図4(a)は、1つの反応用流路群210を示し、図4(b)は、触媒構造体400が装填された反応用流路群210を示す。図4(a)においては、反応用流路群210へ装填される触媒構造体400を説明するために、1つの触媒構造体400を記載する。
図4に示すように、第1変形例において、パーティションを構成する隔壁112は、各々、図2の実施形態と同様に、複数(ここでは、2つ)に分割された部分隔壁で構成され、隔壁112によって、図2と同様に、反応用流路群210を構成する反応用流路212が区画される。従って、図2と同様に、隔壁112の間隙230によって、パーティションの連通部450が構成される。しかし、触媒構造体400は分割されず、図2の間隙330に代えて、本体部410に形成される切り欠き430を有する。具体的には、本体部410は、図2の本体部310と同様に、コルゲート形状に屈曲した薄板材で構成されるが、本体部410の上側及び下側に、一定の深さ(Z軸方向)の切り欠き430が形成されて、頂部422(隆起した上面部)及び底部424(陥没した底面部)が局所的に欠損する。これらの切り欠き430によって、断面形状が長方形の連通路が、本体部310の上側及び下側に、反応流体の流通方向と垂直な方向(Y軸方向)に真っ直ぐ貫くように構成されて、本体部310によって区画された反応用流路212の部分流路及び外部が局所的に相互に連通される。触媒構造体400を反応用流路212に装填した状態における切り欠き430の位置は、隔壁112の間隙230と一致し、切り欠き430の流通方向(X軸方向)の長さは、隔壁112の間隙230と実質的に同じである。従って、切り欠き430によって形成される連通路を通じて、反応用流路212の部分流路と隔壁112の間隙230とが相互に連通し、連通部450において、全ての反応用流路212の部分流路が、反応流体の流通方向と垂直な方向(Y軸方向)に真っ直ぐに連通される。
図5は、本発明に係るリアクタの連通部に関する第2変形例を説明するための図である。図5(a)は、1つの反応用流路群210を示し、図5(b)は、触媒構造体520が装填された反応用流路群210を示す。図5(a)においては、反応用流路群210へ装填される触媒構造体520を説明するために、1つの触媒構造体520を記載する。
図5に示すように、第2変形例においては、図4の切り欠き430と同様の切り欠き540が、触媒構造体520を構成する本体部530の上側のみに形成されると共に、反応用流路212を区画する各々の隔壁512は分割されずに、切り欠き514が各隔壁512に形成されている。つまり、パーティションの連通部550は、間隙230に代えて、隔壁512に形成される切り欠き514によって構成され、本体部530の連通部は、本体部530に設けられる切り欠き540によって構成される。具体的には、隔壁512の上側に、長方形の切り欠き514が形成され、触媒構造体520の本体部530は、図2と同様にコルゲート形状に屈曲した薄板材で構成されるが、頂部532(隆起した上面部)が部分的に欠損するように、本体部530の上側に一定の深さの切り欠き540が設けられる。本体部530の切り欠き540によって、断面形状が長方形の連通路が、本体部530の上側に、反応流体の流通方向と垂直な方向(Y軸方向)に真っ直ぐ貫くように構成されて、本体部530によって区画される反応用流路212の部分流路及び外部が局所的に相互に連通される。触媒構造体520を反応用流路212へ装填した状態において、切り欠き540の位置は、隔壁512の切り欠き514と一致し、切り欠き540の流通方向(X軸方向)の長さ及び深さ(Z軸方向)も、隔壁512の切り欠き514と実質的に同じである。従って、本体部530の切り欠き540によって形成される連通路を通じて、反応用流路212の部分流路及び切り欠き514が相互に連通する。
このように、パーティションの連通部550及び本体部310の連通部を、切り欠き514,540で構成することもできる。
図6は、本発明に係るリアクタの連通部に関する第3変形例を説明するための図である。図6(a)は、1つの反応用流路群210を示し、図6(b)は、触媒構造体620が装填された反応用流路群210を示す。図6(a)においては、反応用流路群210へ装填される触媒構造体620を説明するために、1つの触媒構造体620を記載する。
図6に示すように、第3変形例においては、反応用流路群210において、反応用流路212を区画する隔壁612には貫通孔614が設けられ、パーティションの連通部650は、隔壁612の貫通孔614によって構成される。又、触媒構造体620の本体部630にも、隔壁612の貫通孔614に対応した貫通孔640が設けられ、本体部630の連通部は貫通孔640によって構成される。具体的には、各々の隔壁612の上流側(入口214側)において、中心軸に沿った長方形の貫通孔640が形成され、触媒構造体620の本体部630は、図2と同様にコルゲート形状に屈曲した薄板材で構成されるが、反応用流路212を部分流路に区分する隔壁部に長方形の貫通孔640が形成される。本体部630の貫通孔640によって、断面が長方形の連通路が、反応流体の流通方向と垂直な方向(Y軸方向)に真っ直ぐ貫くように構成されて、反応用流路212の部分流路及び外部が局所的に相互に連通される。触媒構造体620を反応用流路212へ装填した状態において、貫通孔640の位置は、隔壁612の貫通孔614と一致し、貫通孔640の流通方向(X軸方向)の長さ及び高さ(Z軸方向)も、隔壁612の貫通孔614と実質的に同じである。従って、本体部630の切り欠き640によって形成される連通路を通じて、反応用流路212の部分流路及び貫通孔614が相互に連通する。
このように、パーティションの連通部650及び本体部630の連通部を、貫通孔614,640で構成することもできる。
