The Dimethyl Ether Synthesis from Biomass-derived Syngas

摘要：

The synthesis of dimethyl ether from bimass-deriver syngas was carried out in a high pressure fixed bed reactor system over CuO-ZnO-Al2O3/γ-Al2O3.The effect of temperature,pressure,space time and time on stream on CO conversion and dimethyl ether selectivity was studied using biomass-derived syngas which was composed of (H2)/(CO)/(CO2)/(CH4)=52/24/23/1 (V/V).The catalyst samples before and after reaction were characterized by the means of X-ray diffraction (XRD) and nitrogen adsorption.The experimental results indicated that sintering of Cu particles of the catalyst was the main cause of the catalyst deactivation with time on stream
