| Abstract: | As a kind of alternative fuel for diesel engines, attention due to its desirable properties compared with those of traditional diesel fuels. Direct synthesis of dimethyl ether from bio-syngas was studied over a series of catalysts. CuZnFeZr/HZSM-5 catalyst show higher conversion of CO and selectivity of DME than the other catalysts. The experimental parameters, i.e.,reaction temperature, pressure and space velocity were also studied for this reaction. The experiment has been optimized process conditions： temperature 260-270 ℃, the temperature is about 3.0 MPa, and the space velocity is about 1500 h-1. |
