Description
H2O + CO → CO2 + H2 (2)
CO + 2H2 → CH3OH (3)
本反応は発熱反応であるが、気相法では熱伝導が悪いために、効率的な抜熱が困難であることから、反応器通過時の転化率を低く抑えて、未反応の高圧原料ガスをリサイクルするという効率に難点のあるプロセスとなっている。しかし、合成ガス中に含まれる、水、二酸化炭素による反応阻害は受けにくいという長所を活かして、様々なプラントが稼働中である。
(1)一酸化炭素、二酸化炭素の少なくともいずれか、及び水素を含む原料ガスと溶媒としてのアルコールの存在下で反応を行うギ酸エステルを経由するメタノール合成用触媒であって、アルカリ金属ギ酸塩(触媒成分1)に加えて、Pd及び/又は炭酸塩又はギ酸塩としてのNaがCu/MgOの固体触媒に担持されているCu、Mg、Na及びPdを含有する触媒(触媒成分2)を有し、前記アルカリ金属ギ酸塩としてギ酸ナトリウムが存在する場合そのギ酸ナトリウム(触媒成分1)は前記固体触媒(触媒成分2)に担持されていないことを特徴とするメタノール合成用触媒。
本発明者らは、鋭意検討した結果、触媒及び溶媒を反応器を仕込み原料ガスを供給する半回分式の連続反応においてアルカリ金属ギ酸塩に加えて、Pd及び炭酸塩又はギ酸塩としてのNaがCu/MgOの固体触媒に担持されているCu、Mg、Na、Pdを含有する触媒を用いると、一酸化炭素、二酸化炭素の少なくともいずれか、及び水素とアルコール類からメタノールの製造において、高収率で製造可能であることを見出し、本発明に至った。
K2CO3+H2O→2KOH+CO2 (4)
