Beschreibung
Zusammenfassung:	The invention relates to a method for preparing dimethyl ether through methanol dehydration, and belongs to the technical field of catalytic reaction. According to the method, MIL-96 (Al) is used for catalytic reaction, and compared with the application process of a catalyst in the prior art, the method has the advantages that the reaction rate, the conversion rate and the stability are higher. The invention also provides a preparation method of the catalyst in the reaction. The stable MIL-96 (Al) is synthesized by using MIL-110 (Al) as a raw material. 本发明涉及一种甲醇脱水制备二甲醚的方法，属于催化反应技术领域。本方法中使用MIL-96(Al)进行催化反应，相对于现有技术中的催化剂的应用过程，本方法实现了更高的反应速率、转化率以及稳定性。专利也同时提出了该反应中催化剂的制备方法，利用MIL-110(Al)作为原料合成出稳定的MIL-96(Al)。
