CH4+H2O ←→ CO+3H2 …(1)
CO+H2O ←→ CO2+H2 …(2)
本発明にいう「担体」とは、図2(a)及び図2(b)に示す選択透過膜型反応器20を構成する担体22のように、触媒6及び選択透過膜8を配設するための支持体となる部材であり、多孔体からなる隔壁24によって区画・形成された、2以上のガス流路(セル26)を有する筒状体である。このような構造の担体22を用いることによって、触媒6と選択透過膜8とを各々個別のセル26に配設することが可能となる。従って、従来の選択透過膜型反応器のような、触媒と選択透過膜とが同一空間に配設された構造に起因する不具合、具体的には、触媒粉末が選択透過膜に付着して膜表面を閉塞したり、或いは触媒粉末が選択透過膜の構成成分と反応してしまう現象を有効に防止することができる。なお、本発明においては、触媒が配設されたセルを「反応セル」、選択透過膜が配設されたセルを「回収セル」と称することにする。
d=−γ×cosθ/P …(1)
(但し、d:細孔径、γ:液体−空気界面の表面張力、θ:接触角、P:圧力)
本発明にいう「触媒」とは、化学反応を促進させるための成分であり、目的とする反応により当然にその種類は異なる。例えば、水蒸気、二酸化炭素を用いた、炭化水素の改質による水素の生成反応であれば、ニッケル系触媒の他、白金(Pt)系、ルテニウム系、ロジウム(Rh)系等の貴金属系触媒等を好適に用いることができる。炭化水素の部分酸化反応には白金等の貴金属系触媒が、一酸化炭素(CO)のシフト反応の場合には銅−亜鉛(Cu−Zn)系や鉄−クロム(Fe−Cr)系の触媒を好適に用いることができる。
本発明にいう「選択透過膜」とは、特定の成分に対する選択的透過能を有する薄膜状の部材であり、透過させるべき目的成分によりその種類は異なる。例えば、炭化水素の改質反応による生成ガスから水素を選択的に分離・回収する場合であれば、水素に対する選択的透過能を有するパラジウム(Pd)、ないしはパラジウム−銀合金をはじめとするパラジウム合金からなる水素透過膜を使用することができる。この他、選択透過膜としては、シリカやジルコニアからなる水素透過膜、ゼオライト膜、或いはナノ膜等を用いることができる。選択透過膜の製膜法については、所定の透過性能を発現させることができる限りにおいて特に制限はないが、例えば、メッキ法、CVD(Chemical Vapor Deposition)法、スパッタリング法、ゾルコート法等の従来公知の各種製膜法を利用することができる。
本発明の選択透過膜型反応器の使用方法について、図2(a)及び図2(b)に示す選択透過膜型反応器20を用いて、メタンの改質による水素の生成、及び分離・回収を行う場合の例により説明する。この場合、選択透過膜型反応器20としては、触媒6としてメタンの改質反応を促進するニッケル系の改質触媒が、選択透過膜8として水素に対する選択的透過能を有するパラジウム−銀合金からなる水素透過膜が配設されたものを用いればよい。
CH4+H2O ←→ CO+3H2 …(1)
CO+H2O ←→ CO2+H2 …(2)
図2(a)及び図2(b)に示すような、触媒6と、選択透過膜8と、担体22とを備えた選択透過膜型反応器20を作製した。
図3(a)及び図3(b)に示すような、触媒6と、選択透過膜8と、担体52とを備えた選択透過膜型反応器50を作製した。
図5(a)及び図5(b)に示すような、薄膜状の触媒76と、選択透過膜8と、担体22とを備えた選択透過膜型反応器70を作製した。
図1に示すような、触媒6と、選択透過膜8と、反応管2と、分離管4とを備えた選択透過膜型反応器10を作製した。
実施例1〜3、及び比較例1の選択透過膜型反応器については、ステンレス鋼によって構成されたハウジングに装填した状態で評価を行った。このハウジングは、その内部に気密的に隔離された透過ガス流路と非透過ガス流路が形成されており、選択透過膜型反応器において得られる透過ガスと非透過ガスとを分離して別個に回収し得るように構成されている。
Rc=100×Qp/(Qp+Qr×CH) …(1)
(但し、Rc:水素回収率(%)、Qp:回収セル側出口ガス流量(単位:例えばL/分)、Qr:反応セル側出口ガス流量(単位:例えばL/分)、CH:反応セル出口ガス中の水素ガスのモル分率(単位:無次元))
Rp=(Cm×Rc)÷100 …(2)
(但し、Rp:水素製造効率(%)、Cm:メタン転化率(%)、Rc:水素回収率(%))
