Abstract
In this paper, a new catalyst system Cu-Mn-(M)/γ-Al2O3 was developed for the directly synthesis dimethyl ether (DME) from synthesis gas in a fixed-bed reactor. The catalysts with different n (Cu) : n (Mn) ratios, several promoter M (M is one of Zn, Cr, W, Mo, Fe, Co or Ni) were prepared and tested. The results showed the catalysts have a high conversion of CO and a high DME selectivity. The DME yield in tail gas reached 46.0% (at 63.27% conversion of CO) at 2.0 MPa, 275°C, 1500 h−1 with the Cu2Mn4Zn/γ-Al2O3 catalyst.
