| Abstract: | The preparation of catalyst for dimethyl ether synthesis from syngas in one step process is investigated and the characteristics of the catalyst are tested by fixed-bed tube reactor. The effects of active component of catalyst on the conversion rate and selectivity of dimethyl ether synthesis is studied in this paper, and the influence of the preparation method on the catalyst activity is also investigated. Finally the relative ratio dimension of Cu-Zn-A and molecular sieve are optimized, and co-precipitation is adopted as the method of the catulyst preparation. |
