本文研究了采用Ni(CO)4/KOMe均相催化体系由合成气合成甲醇,分别讨论了反应温度、甲醇钾和四羰基镍的浓度以及反应总压对甲醇时空产率的影响,并确定了均相法由合成气制备甲醇可以在很温和的反应条件(T=378K, P=1.8 MPa)下进行.甲醇时空产率一般保持在4 mol/L.h左右.
本文研究瞭採用Ni(CO)4/KOMe均相催化體繫由閤成氣閤成甲醇,分彆討論瞭反應溫度、甲醇鉀和四羰基鎳的濃度以及反應總壓對甲醇時空產率的影響,併確定瞭均相法由閤成氣製備甲醇可以在很溫和的反應條件(T=378K, P=1.8 MPa)下進行.甲醇時空產率一般保持在4 mol/L.h左右.

Homogeneous synthesis of methanol from syngas was studied in the Ni(CO)4/KOMe catalytic system. The influence of reaction temperature, Ni(CO)4 and KOMe concentrations, as well as reaction pressure on the catalytic activity were discussed respectively. The results showed that methanol could be prepared from carbon monoxide and hydrogen under mild reaction conditions(T=378K and P=1.8 MPa). The catalyst activity characterized by Space Time Yield(STY) of MeOH is about 4 mol/L.h.
