| Abstract: | The reaction mechanism of one-step preparation of dimethyl ether was summarized, and one-step preparation process of dimethyl ether was introduced. In Cu-Zn-Zr-methanol catalyst system, the best mass ratio of different components in the catalyst was discussed. The results show that the conversion rate of CO, and the selectivity rate and the recovery rate of dimethyl ether can reach 89.5%, 70.0%and 62.5%respectively when the ratio of Zr, CuO and ZnO is 5:4.5:0.5. In Cu-Zn-Al catalyst system, the best mass ratio of different components in the catalyst was discussed. The results show that the conversion rate of CO, the selectivity rate and the recovery rate of dimethyl ether can reach 90.2%,62.3%and 56.7%respectively when the ratio of CuO:ZnO:Al2O3 is 6:3:1. |
