Abstract:The effect of preparation method and reaction conditions on the catalytic properties of CuO/ZnO/Al 2O 3 and CuO ZnO Al 2O 3/HZSM 5 catalysts in the direct synthesis of dimethyl ether from synthesis gas was studied.The results indicated that the CuO/ZnO/Al 2O 3 catalyst prepared by the coprecipitation sedimentation method and calcined at 350°C and reduced at 240°C exhibited the highest catalytic activity.The best reaction conditions over CuO ZnO Al 2O 3/HZSM 5 catalysts are:temperature,270°C;pressure,4.0MPa;GHSV,1500h -1 ;H 2/CO=2~2 8 and CO 2,5%.
