Title:
METHANOL PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/045327
Kind Code:
A1
Abstract:
The present invention provides a methanol production method in which the stability of a catalyst over time is excellent. The methanol production method according to one embodiment comprises a step for obtaining methanol by bringing a starting gas containing carbon monoxide and hydrogen into contact with a catalyst. The catalyst: 1) contains copper and zinc and has a molar ratio of zinc to copper (Zn/Cu) of 0.3 to 0.45; and 2) has an alkali metal content of 0 to 0.05 mass%.
