A diesel fuel additive has been synthesized from dimethyl ether(DME) by using dielectric-barrier discharging at atmospheric pressure and low temperature. A high conversion of DME has been obtained. The product is a mixture of dimethoxy-containing hydrocarbons with high cetane number, which can be used as a high efficienty diesel fuel additive. The results indicated that the length of discharge gap, reaction temperature and discharge power significantly affected the conversion of DME. At 120℃ and flow rate of DME 30 mL/min the maximum conversion of DME reached 47.20% with a selectivity of liquid product more than 39%.
