Description
本発明は、メタノールの部分酸化により合成ガスを調製する方法に関するもので、メタノールフィードストック(methanol feedstock)が天然ガスよりもコストが安いときに用いられる。より具体的には、メタノールとCOから酢酸を調製する方法に関し、COは、メタノールフィードストックの部分酸化によって生成された合成ガスから分離されている。
本発明の詳細な実施例を開示する。なお、開示される実施例は、本発明の単なる一例であって、様々な形態で具体化されることができる。本明細書の中に記載した具体的な構造及び作用の詳細については、限定することを意図したものではなく、特許請求の範囲内において変更可能な単なる例示にすぎないものである。
CH3OH←→CO+2H2
CH3OH+H2O←→3H2+CO2
所望により、以下に示す逆シフト反応において、二酸化炭素と水素の反応によって一酸化炭素と水を生成し、一酸化炭素の生成量を増加させることもできる。
CO2+H2←→CO+H2O
C 2 H 4 +AcOH+1/2O 2 →VAM+H 2 O
主たる副産物CO 2 は、次の反応式によって生成される。
C 2 H 4 +3O 2 →2CO 2 +2H 2 O
この方法では、約7〜8質量%のCO 2 が生成される。一般的には、約100,000メートルトン/年(MTY)のVAMを生産するVAMプラントでは、およそ35,000MTYのエチレンを必要とし、5,000〜10,000MTYのCO 2 が生成される。
