文摘
- •
The rate of formaldehyde formation reached a significant growth in a microchannel reactor.
- •
Productivity in a micro-channel reactor is 10-fold higher than in a fixed-bed tubular reactor.
- •
The reaction operated safely within the explosive range of methanol-oxygen mixture.
- •
The methanol conversion decreased by only 3–12% after operation for 100 h.
