Description
本願は、2008年09月30日に日本出願された特願2008-253213に基づいて優先権を主張し、その内容をここに援用する。
前記複数の供給手段は、前記反応器の底部に設けられた第1供給手段と、当該第1供給手段よりも高い位置に設けられた複数の第2供給手段とを有していてもよい。
前記各第2供給手段は、前記反応器の横断面上に設けられた複数の供給口を有していてもよい。
この場合、反応器の横断面方向においても複数の供給口から合成ガスが反応器に供給されることになるため、反応器全体における合成ガスの分圧をより均一にすることができる。
この場合、例えば反応器の周囲の環境に応じて、前記各第2供給手段から供給される前記合成ガスの流量を個別に調整できるため、柔軟な処理が可能となる。
前記各第2供給手段から供給される前記合成ガスの流量は、前記反応器のガス空塔速度に基づいて決定されてもよい。予め決定する手段としては、例えば実験やシミュレーションを行っておき、当該実験又はシミュレーションの結果に基づいて前記各第2供給手段から供給される前記合成ガスの流量を決定することができる。
前記第2供給手段は、前記反応器の中心を通るように設けられた基幹部と、当該基幹部に接続され、前記反応器と同心円の環状に形成され、それぞれ径の異なる複数の環状配管とを備え、前記複数の供給口が、前記複数の内部配管に形成されているものでもよい。また、前記第2供給手段は、前記反応器の中心を通るように設けられた基幹部と、当該基幹部から水平に延びる複数の分岐部とを備え、前記複数の供給口が、前記複数の分岐部に形成されているものでもよい。
以下に添付図面を参照しながら、本発明の第1実施形態について詳細に説明する。なお、本明細書及び図面において、実質的に同一の機能構成を有する構成要素については、同一の符号を付することにより重複説明を省略する。

また、水素分離装置26は、脱炭酸装置20又は気液分離器18と気泡塔型反応器30とを接続する主配管から分岐した分岐ライン上に設けられる。この水素分離装置26は、例えば、圧力差を利用して水素の吸着と脱着を行う水素PSA(Pressure Swing Adsorption:圧力変動吸着)装置などで構成できる。この水素PSA装置は、並列配置された複数の吸着塔(図示せず。)内に吸着剤(ゼオライト系吸着剤、活性炭、アルミナ、シリカゲル等)を有しており、各吸着塔で水素の加圧、吸着、脱着(減圧)、パージの各工程を順番に繰り返すことで、合成ガスから分離した純度の高い水素ガス(例えば99.999%程度)を、連続して供給することができる。
各供給配管T2~T11に接続される内部配管30cが気泡塔型反応器30内のスラリー30sの収容高さに対して均等に配置されているため、合成ガスはスラリー30s内に対して高さ方向に均一に供給される。また、ガス供給口30eが平面視で気泡塔型反応器30内部断面の全体に亘って形成されているため、合成ガスの分圧が平面方向においてもより均一となる。高さ方向及び平面方向にそれぞれ均一に供給された合成ガスは、合成工程において、スラリー30sの当該高さ方向及び平面方向の全体に亘って均一に合成反応を起こす。
次に、本発明の第2実施形態を説明する。上記実施形態と同一の構成要素については、同一の符号を付してその説明を省略する。本実施形態では、供給配管T2~T11及び流通管T13の構成が第1実施形態とは異なっているため、この点を中心に説明する。
同図に示すように、本実施形態では、供給配管T1~T11が例えば上記の圧縮機(不図示)が設置された配管から分岐するように設けられている。また、気液分離器38で分離された未反応の合成ガスを流通させる流通管T13が供給配管T1のみに接続されている。
