| 摘 要： | 采用共沉淀法、浸渍法、机械混合法、胶体沉淀法制备了成分相同的二甲醚合成催化剂，通过X射线衍射法和电镜扫描法对催化剂进行了表征。结果发现，4种制备方法中，浸渍法制备的催化剂物相效果最理想，各成分分散均匀，粒径较小，无结块、烧结现象。 |

| Abstract: | Catalysts with the same composition for synthesis dimethyl ether are prepared by co-precipitation,impregnation,mechanical mixing,colloidal precipitation method.The catalyst is characterized by DEM and XRD.The rulsts show that the effects of catalyst prepared by impregnation are optimal in four methods: particles distribute in a steady uniform,crystal size is small,has no sintering phenomenon. |
| Keywords: | Dimethyl ether Catalyst Preparation method Characterization |
