文摘
- •
DME (Dimethyl ether) synthesis with CO2 utilization is analyzed thermodynamically.
- •
Single step and two-step DME syntheses are studied and compared with each other.
- •
CO2 addition suppresses CO conversion in MeOH synthesis but increases MeOH yield.
- •
The performance of the single step DME synthesis is better than that of the two-step one.
- •
Increase CO2/CO ratio decreases CO2 conversion but increases CO2 consumption amount.
