PROCESS FOR PREPARING DIMETHYLETHER FROM METHANOL |
摘要 |
The present invention relates to a process for preparing dimethyl ether from methanol. More particularly, this invention relates to an improved process for preparing dimethyl ether with high yield useful as a clean fuel as well as a raw material in chemical industry performed via a catalytic system, wherein dehydration of methanol is first carried out by using a hydrophilic solid acid catalyst and then subsequent dehydration of methanol is carried out continuously by using a hydrophobic zeolite solid acid catalyst in the concurrent presence of unreacted methanol, dimethyl ether produced and water. |
