| Abstract: | Dimethyl ether (DME) synthesis in slurry bed was investigated by using different methanol synthesis catalysts and different dehydration catalysts. It was found that methanol synthesis catalyst had great effect on DME synthesis, and a better methanol synthesis catalyst would be favorable for DME synthesis. The dehydration catalyst showed different performance in DME synthesis due to not only the acid strength, but also interaction between strong and weak acid sites. |
