文摘
- •
Cu-based catalyst performance was studied in methanol and direct DME syntheses.
- •
Methanol dehydration affects methanol formation kinetics negatively.
- •
Water, formed by methanol dehydration, can be the cause of the observed effect.
- •
DME is practically inert over the methanol synthesis catalyst.
- •
Addition of water to the feed decreases methanol formation rate significantly.
